A round zipper long wallet made of galusha (stingray leather).
Galuchat is also known as the "jewel of the sea," and is so named because of its unique luster and shine.
It is made of calcium phosphate, the same material as human teeth, and is said to be durable for 100 years (cowhide is generally said to last for 30 years). It is native to Southeast Asia, mainly Thailand, and has been popular in Japan since ancient times as a lucky charm, and has been used for sword sheaths. (Even today, its beauty is preserved in the sheaths of swords and other items stored in museums.)
Due to its durability, processing it requires skill, and the name "galuchat" comes from the name of a French leather craftsman who once specialized in processing stingray leather.
If you try to sew like that, the needle will break.
This time we used two types of garfish.
Black → With grain. The surface is not scraped, so it has a grainy texture and a sparkling luster.
Tiffany blue → Gin-suri. The surface is scraped and flattened, giving it a smooth, glossy finish.
This was the first time we had handled this material, but we were enchanted by its beauty as we worked on it.
The bag is completely hand-sewn, and the interior is made of pigskin. The light and durable pigskin is bent to increase strength in the card compartment and the top of the pockets, and a lining is applied to increase tension and strength.
The entire piece is hand-sewn, with tension adjusted for each stitch, resulting in a three-dimensional, sturdy seam.
