When considering a slim wallet, if it has a typical design where cards and coins do not overlap, everyone will worry at least once that the cards will fall through the gaps.
The trade-off between "thinness" and "holding strength" In fact, with wallets that limit the number of cards they can hold, the holding strength weakens when there is not much inside, which often leads to regret when a card is dropped.

In the case of the SOLAHANPU Tynd, which provides peace of mind through its structure , the card pockets are naturally covered when the wallet is closed, so there is no need to worry about cards falling out. If you open the wallet with only a few cards, you can still rest assured because there is an extra card pocket cover.
The SOLAHANPU Tenuis also has a "twin card slot" that minimizes the number of cards stacked, and when the wallet is closed, it naturally covers the card slot, so there is no need to worry about cards falling out.
We physically eliminated the drawbacks of the card retention system that make it difficult to use . It's not just about being thin, but about having the retention strength to continue using it with confidence. We believe that this is the integrity of a tool.
