I used these at daycare as spares. I used bleach to try and remove stains, and the area below the Velcro on the front has slightly discolored, but otherwise, they are in good condition. They have non-slip soles and are made of a material that allows for safe wear ◎ I think the original price was around 3000 yen. I'm selling them at a low price to someone who can use them for playing outside, etc. ^_^
