The thin wallet has a design that makes it seem like the contents might fall out, and the manufacturer says they've taken measures to address this, but...

When researching slim wallets, common concerns include "cards might fall out" and "the coin purse seems difficult to use and coins might spill out." Of course, manufacturers don't ignore these issues; they implement features to prevent cards from slipping and add lids to coin compartments, but some people still feel uneasy.

However, I'd like you to stop and think for a moment.

Doesn't that solution assume the user will "be careful not to let it fall"? "It'll be fine if you open it at this angle," "It won't spill if you hold it firmly here"... Isn't that essentially the user having to adapt to the wallet, which is supposed to be a tool?

No matter how many countermeasures are in place, if you feel even a momentary jolt of tension when you're in a hurry at the checkout counter or when you unexpectedly take something out of your bag, that's proof that there are still design issues that need to be addressed.

What SOLAHANPU consistently employs in the Tenuis series is not countermeasures using outlandish gimmicks. It is a physical "encompassing capacity" based on the conventional bi-fold structure.

• Simply close it with a click: Whether closed or open, there is no risk of items falling out, regardless of the quantity.

• Peace of mind without having to think about it: Even if you turn it upside down, the contents will be held securely without having to learn the "correct way to hold it."

We have aimed for a level of reassurance that goes beyond the stage where manufacturers talk about "countermeasures," a level where "there is no need to feel anxious in the first place."

Being freed from the stress of "using it in a way that it won't fall"—that's what I believe truly smart design brings in value.
