K2 Inline Skates Junior CHARM Boa 19.5-23.0cm These skates have been used and show some scratches, but there is no damage, and they should still be usable. The size is adjustable in 5 steps. The Boa system allows for easy tightening just by turning the dial, so children can use them independently. To loosen, pull the dial to release the lock. The aluminum base provides high rigidity, and the wheels spin smoothly. Kids kids junior
