Black earmuffs with a wire for a perfect fit. - Color: Navy - Features: Wire for a good fit - Size: Free size (earmuff diameter approx. 13cm) Thank you for viewing. I bought these a few days ago for my child, but they seemed too big and likely to slip off while riding a bicycle (although they haven't actually ridden a bicycle). So, I repurchased a smaller size. Only tried on at home. 【Product Description】 Ear muffs that are easy to wear for everyday use, commuting to school, going out, and for cold weather protection.
