This is a Funassyi coin case. One side has a 3D design that changes slightly. It's a set of 3. It was an amusement prize from quite a while ago. I haven't used it to hold coins, but it's a used item that has been stored in a drawer or displayed for a long time. There are some fold marks, minor stains, and some loose threads on the inside. It will be placed in a water-resistant bag and sent via Yu-Packet Post Mini, compressed to fit within 3cm. Please refrain from purchasing if you are concerned. Thank you.
