100% Cotton This is a regular-weight, soft, and stretchy knit fabric. It fits snugly around the neck. Suitable for those who are sensitive to synthetic fibers. You won't want to be without it in the cold season. I recommend wearing it when you sleep because it keeps you warm:⁠-⁠* It can also be used as a turban or ear warmer. It's difficult to convey in photos, but knit fabrics vary in thickness and stretch. Thank you for your understanding >⁠.⁠< Handmade items are discounted by 150 yen from the second item onwards. Thank you very much! ~(*´∀`*)ノ
