The color is a colorful pink. It's used by putting it on your wrist, like in the second photo. The length is as shown in the photo. The wrist circumference is small. When it's cold, putting it on your wrist makes you feel warm and cozy (^ω^) How about it for protection against the cold in the mornings and evenings during the upcoming cold season? * I knit with care when knitting. This was knitted by an amateur like myself. I would appreciate your understanding and acceptance.
