Only 6mm thin
Why a thin wallet?
As the use of credit cards and electronic payments has dramatically increased over the past decade or so, people are becoming increasingly aware that they need to carry less cash and want a smart wallet that is less bulky, instead of the traditional large, thick, stiff, bulky wallets. In fact, the number of thin, small, compact wallets continues to grow and has established itself as a new genre, and is even in the process of becoming established.
Two products in our "Tenuis" series have achieved crowdfunding support of JPY 44 million and JPY 24 million, respectively, from 2019 to 2021. This product is the 4th generation successor to those products. In the compact wallet industry, many wallets are designed to be thin by not overlapping coins and cards, but "Tenuis" pursues thinness and ease of use based on a different theory.

Features of the latest version of Tenuis
Structure pursuing thinness
Structure that prevents stowed items from overlapping
Combination of cowhide and goatskin leather - "Tenuis" is made of high-grade Italian oil leather with a traditional bucketta method on the outside and thin, strong, and elastic goatskin leather on the inside. The leather has a texture like Japanese washi paper and has a fluffiness that changes its luster and color as it is used.
Twin card slots - The card slots are divided into two places to distribute the thickness, but the area is only large enough for two cards side by side. The card pockets are folded in and sewn from the inside, and the thinness, elasticity and strength of the goatskin leather make this possible.
Twin coin pockets - The coin pockets are divided into two sections to reduce overlap, which contributes to the thinness of the bag, and each pocket is equipped with a partition structure to prevent coins from moving up and down.
Concealed pocket for extra capacity
Hidden pockets - There are two hidden pockets on the back side of the wallet. Each pocket has a large space for cards and two slots for keys. The hidden pockets are designed to fit in the original space, so there is no need to increase the thickness of the wallet in order to accommodate the hidden pockets.
Large capacity in a thin wallet
Thin wallet but large capacity - Thin wallets tend to have a limited capacity, or you may think that you have to limit the amount of items you can carry in them.
