Thank you for viewing. This is Okamoto's Marude Kotatsu ribbed design ankle warmer in gray. I heard it's better not to cover your toes when sleeping. It's made of stretch material for a comfortable fit, but it didn't suit me because my toes get cold. This is a new, unused item, but it does not have a bag. - Color: Gray - Design: Ribbed - Features: Stretch material - Size: Free size
