While leaving a gentle impression, it's minimal. "Wooden Paper Holder"

A simple design stripped of unnecessary elements. It is a wooden water-related accessory that coexists with architectural beauty and meticulous craftsmanship in its details.

★ One by one, with care. A commitment to handwork. A simple structure that just holds toilet paper on an approximately 2cm wide arm. Each design is made by cutting materials from a single board. From the front, you can enjoy the unique expressions of natural wood, each with its own "grain," and from the side, you can see the cross-section, which reveals the growth rings of the wood, known as "mokuguchi." What I personally want you to focus on is the wood grain in this cross-section. It's a small detail, but when you look at the dense wood grain pattern depicted within just 1.5cm of thickness, you can't help but be impressed by how, despite its light appearance, it is made of solid hardwood. To maintain sharpness, the beveling of the corners is kept to a minimum. Only the inner part of the arm where the paper core touches is made larger for easier rotation, and each small part is finished by hand. For the finish, we adopted a hybrid paint that mixes natural plant oil with urethane, aiming to achieve both beauty and practicality by combining the moist feel of an oil finish with the durability of urethane coating. The included small brass screws for wall mounting, while tiny, serve as a sparkling accent.
