Fluffy Neck Warmer Gray From the time of purchase, something like a red thread has been mixed in with the bag. Please purchase only if you don't mind (see photo 7). This neck warmer is stretchy and extends very well, making it easy for even a child to put on and take off♪ (By the way, adults can also wear it) It will be packaged in the compressed state it was in at the time of purchase. Thank you very much(^^)
