This is an adjustable-size inline skate set. The inline skates are a five-wheel type on one side with auxiliary wheels. Using the included dedicated shaft and hex wrench, you can change from the auxiliary wheel type to the inline skate type. - Brand: EASY INLINE - Size: M (20cm - 23cm) - Color: Passion Blue - Accessories: Helmet, protectors (wrist guards, elbow pads, knee pads), hex wrench, shaft, insoles, instruction manual - Adjustable size: 20cm - 23cm The wheels and brakes are dirty, but they are not worn, so I think you can still play with them. The original box is tattered. Thank you for looking.
