Hello. This is a rather stylish safety helmet for nursing care. The size is M. The head size is 55-57cm. The color is pink. Usage frequency: Purchased before this summer, used indoors 4-5 times. The impact-absorbing material and the helmet body can be separated, and it has a chin strap for wind and fall protection. It's offered at a low price. My mother no longer needs it as she has entered a facility, so I am waiting for someone who needs it to purchase it.
