Moonstar, size 16cm. The Kuromi-chan forehead mark lights up with every step. (Confirmed) I wore these for two months, but I'm selling them because my child outgrew them. The batteries still seem to be working, so they light up, but I don't know when the batteries will run out. The Velcro straps are removable. I cut off the tag because it had my child's name on it. Please understand that these are used items before purchasing. Also, to reduce shipping costs, I will send them via Yu-Packet Plus. Size: 16cm - Color: Purple - Design: Character design - Material: Mesh - Closure: Velcro
