Thank you for viewing. This is a kids' helmet from RANGS JAPAN. The size is 48-54cm. I purchased it for use with roller skates. I have used it about twice. There are some minor scratches, but it is in relatively good condition. I inspect the item carefully, but there may be small oversights. Please purchase if you understand that this is a used item, has been inspected by a non-professional, and has been stored at home.
