I'm unsure of the purchase period or how many times it was worn. Size: 52cm There is some fuzzing. I apologize if I missed anything else (;_;) It has a string, but I've lost the part used for adjusting the tightness. The color may appear different depending on the lighting during the photos. If you have any concerns, please contact me in the comments section. I will fold it and ship it via Yu-Packet Post. Please understand this before purchasing!
