How to Make a Wet-forming bag
The technique of ‘wet-forming’ utilizes the properties of case leather, where the leather is wetted in water, reshaped, and then allowed to dry into that form. This technique is commonly employed for shoes and harnesses.
To adapt this method to bags the size of a laptop component, we took inspiration from the production techniques of Japanese drums. The angle of roundness is adjusted multiple times, and while maintaining ideal sharpness, we have successfully created a unique roundness that cannot be achieved through sewing, resulting in an iconic bag unlike anything seen before.

Making Processes
A normal bag is made quickly because only the leather is cut before sewing.
Wet-forming takes over a week. Shaping vegetable-tanned leather takes time, but the craftsman wants to create something good.

Deciding the design
To achieve optimal sharpness, we explore various approaches, considering what is most practical and convenient.
Making wood molds
Turn the design on the desk into a real bag by making a wood mold for the leather.
Cutting the leather
Cut leather larger than mold.
Wetting the leather
Pressing the leather on the wood mold
Strike the leather against a tree
After the leather has been shaped to some extent, strike the leather against a tree to remove the mold.
Drying about 3 days
Removing it from the mold.
Once the leather shape has been locked, remove it from the mold and allow the inside to dry for approximately three days.
Cutting the excess leather.
