Gravity-driven insights enable "automatic thickness control" with a coin divider.

In many manufacturers' slim wallets, the coin purse tends to be a compromise. However, as you use the Tenuis 3rd generation coin divider, you'll realize that it's not just a divider, but a device that "automatically controls" the thickness.

During everyday actions like putting your wallet in your pocket or holding it in your hand, coins move around due to gravity. This divider prevents coins from moving around too much, distributing them to keep the wallet slim. There's no need to arrange your coins neatly yourself. Just toss them in, and the wallet will automatically try to maintain its slim profile. This "hands-free" feature is surely what busy modern people need.

The design is so tight that it doesn't leave any room for receipts to overflow, yet you can reach all the way to the back when needed. These seemingly contradictory elements are supported by a single wall—the divider. The more you understand the structure, the more you see the almost obsessive attention to detail put into this tiny partition.
