Turtleshell bicycle helmet by Nutcase - Size M

Bicycle helmet by Nutcase. Fun, green turtleshell design. Removable/optional visor insert. Adult unisex Size M, 22-23.5" or 56-60cm. Only used occasionally when renting bikes since I do not own my own bicycle. For more comfort, I added my own softer black fabric cutout atop one cushion with fabric tape, but it is removable. No accidents, but some white streak-shaped scuff marks from stuffing into my backpack with my other belongings. Pretty good secondhand condition. From a nonsmoking home.
