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.
