Unused item purchased 3-4 years ago. Only tried on. It was stored folded in half inside a fabric case. Therefore, it's creased when taken out. The material is fabric on the outside, and the bottom is likely synthetic leather or vinyl. It's soft and lightweight. It's not very thick and is simply constructed. The heel is shallow, so the hold feels weak. Wearing socks with these slippers will help prevent them from slipping off due to friction. It's not designed for cold protection; wearing them in a gymnasium, school building, or facility in winter will cause cold feet. There's no washing label, but I think it can be hand-washed. The color in the image looks purple, but the actual color is navy. To fit the Mercari shipping size regulations, I plan to remove it from the fabric case and package it to reduce the thickness.
