GLAF Children's Bicycle Skateboard Helmet and Protector Set. I'm selling this because it's no longer needed. All items are size S. For ages 3-8, head circumference 48-54cm (from the purchase site). In the first photo, from top to bottom are elbow pads, knee pads, and wrist guards. There is a scratch on the top of the helmet (photo 5). The size can be adjusted by turning the dial on the back in the second photo. This is a used item that has been used by a child, so please understand. Thank you.
