This item was previously purchased by myself from the Supreme online store. It is definitely authentic, so please don't worry. The size is 26.5cm, and it feels like a 27cm size to me. I haven't worn them much, so I think they are in good condition. Please check the photos carefully before purchasing to confirm the condition. Please note that returns are not accepted to prevent product substitution. *No accessories included. #Supreme #AIRForce1 #シュプリーム #エアフォース1 #nike #ナイキ
