Designed by artist Marlies Plank, the Effetto farfalla Coin Pouch combines stunning Italian visual inspiration with practical functionality. This minimalist coin holder uses Tyvek®, a lightweight, durable material that handles daily wear without zippers, buttons, or snaps. The genius of the design lies in simplicity: coins stack automatically within the pouch's structure, staying secure without bulk. Slip it into a pocket, pack it for travel, or keep it on your desk for loose change. Whether you pair it with our Slim Wallet for everyday carry or use it standalone, this compact coin holder keeps small items organized exactly when you need them. Effetto farfalla means "butterfly effect" in Italian, reflecting Plank's signature visual language. Like all Paperwallet products, it's built to last through folding, bending, and regular use.
