What we value most in design is not decoration, but **rationality**.

Why shouldn't cards be stacked? Why do we insist on materials like canvas and ultra-thin leather? Because it's the most direct solution to eliminate uncomfortable bulges in pockets, avoid ruining trouser silhouettes, and never sacrifice ease of access.
Unnecessary complex gimmicks or superficial design are pointless. "Thin, strong, easy to use." Pursuing this rational functionality to its extreme naturally led us to our current, stripped-down form.
"Function becomes beauty." SOLAHANPU products are born from this belief.
