The gray reflective logo and dotted pattern on both sides are simple and stylish. Made with double-faced fabric for durability, warmth, and a smooth feel, making it suitable for sports and everyday use ◎ Hardly used, in excellent condition. My son couldn't fit his head through it, as it was too small. Color: Black Size: S/M Length: Approximately 22cm Width: Approximately 20cm Price: 2090 yen It has some stretch, but it's a snug-fitting neck warmer. It can be used by a 6-year-old, but it might feel a bit small when putting it over the head, but this is just my personal opinion.
