The ideal of living solely through smartphone payments is somewhat different from reality. Battery failure while out and about, communication problems during payment, or stores that only accept cash—when faced with such unexpected situations, having only a smartphone leaves you helpless. Even aiming for a completely cashless society, you still need some extra cash.

So, I'd like to propose a wallet so thin you'll forget you're even carrying it, a minimal "insurance" item. SOLAHANPU products are designed to carry a few cards and some spare cash in ultimate flatness. Your smartphone is your main device, but in case of an emergency, this thin wallet will come to your rescue.
It's not about "carrying nothing," but about "making yourself unaware of what you're carrying." It's the perfect shape for carrying spare cards and cash alongside your smartphone. Choose this "forgettable thinness" as one element to complete your modern, smart lifestyle.
