I purchased this in Vietnam, but the size didn't fit, so I'm selling it. This is a half-helmet from MUJI. It has a lightweight ABS shell and is well-ventilated for a comfortable fit. It comes with a removable sun visor (※no shield) to protect against sunlight, light rain, and dust. The soft interior and quick-release buckle make it easy to put on and take off. Recommended for commuting, going to school, and short-distance travel. • Material: ABS (outer shell), EPS (impact-absorbing material) • Features: Lightweight, good ventilation / Wide field of vision / With sun visor • Design: Simple and sporty • Country of origin: Vietnam
