Child helmet size Small, for scooting/biking etc (Raynes Park SW20)

Looks in good condition, although likely dropped on the floor a few times by my child, so it comes with no guarantees. Grown out of. Size is 52-56cm (size small, normally suitable for primary school children).
There's a chin strap with soft chin protector and buckle in good condition, padding on the inside, and an adjustable size system to get a good fit.
