Easy installation with just a door replacement" - The wooden "custom flush door" that can be ordered in millimeter increments is essential for renovations. You can customize not only the height and width of the door but also its thickness, allowing you to take advantage of the existing door space and simply "replace the door.

A wooden flush door that can be custom ordered in size. It is ideal for new constructions as well as for replacing fixtures in renovations, as you can order the thickness, width, and height.

★Size customization is essential for renovations. Whether you are completely redesigning the layout and interior from scratch or just want to change the doors during a small-scale renovation that involves altering the finishes of floors and walls, we introduce wooden flush doors that can be customized down to the millimeter. A flush door is a type of door that has a ladder-like frame with surface materials attached to both sides. Its hollow structure makes it lightweight, and it features a flat surface, making it widely used as interior doors in homes. Generally available doors are often of standard sizes, and if you want a wooden door with a natural texture to be custom-sized, it was previously only possible by requesting a craftsman. This wooden flush door is sold without a door frame, just the door itself. You can customize the height, width, and even thickness of the door, allowing you to "replace just the door" while utilizing the existing door space. To make it easier to achieve a unified style for the doors throughout your home, we have managed to offer these custom-sized products at an affordable price through factory production. This door is one you will definitely want to use not only during renovations but also when building new homes.

A Matsunomi door that evokes the charm of a bygone era from its presence.

Despite being a flush door, MATSU Romantic DOOR intentionally uses a wooden door. Of course, it's also good to take advantage of the wood grain. It reminds us of the good old days.

It is a push-pull type door handle that is neither a doorknob nor a lever handle, with a unique design and functionality.

★Release of Occasion I am drawn to products that are labeled as "for commercial use," which are rugged and specialized for functionality. While they may be over-spec or out of place for everyday use, many people find the aesthetic beauty of their specialized functions appealing and are incorporating them into their interiors. The one-touch door handle was originally designed for use primarily in hospitals and research facilities. The handle, made from cast aluminum in a unique shape, features embossed markings of "PUSH" and "PULL," giving it a presence that ordinary door knobs lack. While it may feel unfamiliar when used in a home, that sense of incongruity adds a distinctive touch to the space. It is a door handle characterized by being "different from the usual." ★Touching a Chunk of Aluminum The lever part is a casting made by pouring molten aluminum into a mold. When touched, it conveys a substantial material feel unique to metal. The voluminous size and shape typical of commercial use, combined with the muted sheen from anodizing, bring an industrial atmosphere to the door. There are two types of shapes available, with lever widths of 50mm and 30mm.

Wooden pine door. Since it is offered in an unpainted state, it can transform into a fixture with a variety of expressions depending on the finishing method.

★Let's Work Hard on the Fixtures It's just fixtures, but it's also fixtures. Even a single door can greatly influence the impression of a space, which is the nature of these fixtures. Even if the space itself isn't particularly remarkable, simply making a single door stand out can align the entire area with that aesthetic. ★I Want a Wooden Door The construction industry is flooded with ready-made doors. Many people feel distrust towards unnatural appearances that look like wood but aren't, the odd lightness, and the unique plastic feel. After all, at least the doors that are visible should be made of real wood and be proper doors, right? Having a carpenter make one is an option, but it can be quite expensive, and conveying the desired image can be challenging. Antique doors are also difficult to handle and require a chance encounter. What you want isn't always available at the right time and price. This is a door that I hope those in such a situation will seriously consider. *Continues with "Basic Information" below↓*

Cabinet doors made of pure pine wood. They can be used as storage doors or small interior windows. Since they are unpainted, you can paint them in your favorite color.

★The Shape of Longing Storage doors seen in American movie kitchens. Louvered windows reminiscent of European shutters. Yes, I admit I have a bit of admiration for them, sorry. Although I have a preference for Japan, I actually like these kinds of things a little. In Japan, due to the sliding door culture, many doors slide left and right even for small windows, but I find the small swinging doors charming and want to incorporate them. While sleek, minimalist designs without presence are nice, this door, with a moderate design that is neither too simple nor too country-like, retains a certain warmth without being overly assertive. ★Wooden Doors Generally, residential doors are often made with PVC materials. I’m not denying the ready-made products from manufacturers at all, but they do tend to give a somewhat cold, hard, and cheap impression to the space. On the other hand, it is possible to have everything made of wood by a carpenter, but there are often cases where the cost does not justify it. On the other hand, this door is mass-produced in a factory using solid pine wood. It is cheaper than handmade options and has a softer appearance than sheet-covered doors. Even with the same white color, the white of the sheet and the white painted on wood, or the same wood grain, the printed wood and real wood are indeed different. It’s a curious thing.

Hardware designed for commercial use in ships for over half a century is now being used in homes. The performance that has been continuously utilized on board, as well as the beauty of the form born from its functionality, are both appealing.

★Shapes Shaped by Rough Waves We have gathered hardware around doors that has a strong presence, which we hope will catch the attention of those who love parts. In fact, these are parts currently used on ships. Lever handles and door knobs may look no different from hardware intended for homes, but they are originally designed for use on the sea, exposed to sea breezes and constantly swaying with the waves. The weight and pleasant operability become apparent when you actually touch them. The functions that have evolved uniquely have specific reasons related to maritime use. For example, the grip end of the "lever handle" is curved to make it easier to hold when swaying. Additionally, to respond to sudden troubles, screws are visible from the front for easy removal, and parts are secured with bolts instead of being welded together, making them very practical. The structure born from considerations for maintenance has also become part of the design. Shapes born from necessity embody functional beauty. They are perfect for adding accents in simple indoor spaces. It would be a waste for them to be used only on ships! Therefore, we have gathered items that can also be used in homes, offices, and stores.

A timeless basic design handle that has been passed down unchanged for over 70 years.

Founded in 1946 in America by Adolf Schkopp and Karl Reinhardt, Kwikset is said to have revolutionized locks in residential settings with its outstanding design at the time. This design legacy is still firmly upheld today, and the "ACE DOOR" features a handle called "HANCOCK," which has hardly changed in design since then. With a slightly smaller grip ball, its timeless basic design pairs perfectly with the flat panel of the ACE DOOR. The structure utilizes double torque springs to stabilize operation and achieve smooth movement, ensuring that even the finer details are well taken care of.

When buying new cosmetics, while the bottle design is important, what catches the eye first is definitely the "box." When faced with a selection of many cosmetics and unsure of which to choose, it often comes down to making a "package purchase," similar to impulse buying based on the cover. This time, we asked our long-time partner, the cosmetics manufacturer Kurecos Co., Ltd., why they continue to create packages with Kaypack. 【I can hardly remember when we started working with Kaypack】 We began our dealings with Mr. Kita (Kaypack) over 20 years ago, so long ago that I can hardly remember the beginning. In the early days, we relied on another packaging company. However, since starting our relationship with Mr. Kita (Kaypack), we have entrusted the majority of our packaging production to them. There is a mutual understanding developed over our long relationship, and the sense of security that comes from knowing they understand everything makes it easy to request work from them. There is a level of stability that allows us to build trust.

The "Hybrid Joint TCF Type" is a bridge expansion device designed for the Tohoku region that responds to "compacted snow," which occurs due to vehicle traffic after snowfall. It meets the 10kN snow load standard set by the Tohoku Regional Development Bureau. Additionally, it adopts a structure known as the "face plate type," which ensures that the water-stopping material does not become exposed on the surface, and it comes standard with "secondary water-stopping material." By employing a double structure, it reduces the risk of leakage and achieves higher water-stopping performance. Furthermore, to prevent snowplow blades from getting caught on the expansion device, it also comes standard with a "snow removal guide plate." This not only protects the product itself but also considers safety during snow removal operations.

Castem Co., Ltd. and Castem Global Group's Castem Vietnam held a completion ceremony for the newly established Vietnam factory in Quang Ninh Province, Northern Vietnam, in January 2026. This is the first time our group has expanded into Vietnam, and this factory will be our seventh overseas production base. After the planned second phase of construction, it is expected to become the largest production base in the group in the future. The factory will manufacture lost-wax precision casting parts used in semiconductors, precision machinery, and construction machinery. We chose Vietnam, where economic growth is anticipated, as a new production base for our main business of lost-wax precision casting. Currently, we are advancing prototype production and plan to start mass production by the end of May 2026. Once the second phase of construction is completed by the end of 2028, we will ultimately be able to produce one million units per month (with a product shipment weight of approximately 120 tons per month). On the day of the ceremony, about 100 participants, including business operators and local stakeholders, attended and toured the various processes such as mold making, casting, and processing. Although we are starting with a compact system in terms of equipment and personnel, we will continue to take on challenges and advance our business to a new dimension.
