A set of pads for children learning to inline skate, skateboard or ride a scooter. The mesh bag holds three pairs, six parts in total: two knee pads, two elbow pads and two wrist guards, all in the same blue.
Each part is a curved plastic shell with straps that close around the leg or the arm. The wrist guards also have a splint on the palm side, which you can already make out through the mesh.
The header card reads 'Match track of the street - Skating-Sports', with a strip along it showing the whole range. Note that the helmets pictured there are not in this pack: you get the six pads and the mesh bag. This version is size S.
A set like this is usually bought together with a first pair of skates or a scooter. The mesh bag then does duty as a storage bag, so the six parts stay together until the next time.
