100% cotton Made in Japan While I don't see any stains like those on the GUNZE Gunze Three-Quarter Sleeve Sleeves, size M, which are listed separately, I haven't opened it, so I can't be sure about the inside. There might be stains, so please refrain from purchasing if you are concerned. There is dirt on the adhesive part of the package. Please purchase only if you don't mind the details and just want to wear it! I will fold the first image in half and send it as is in an envelope. Please refrain from purchasing if you are concerned about the packaging. ******************** I have tried to provide detailed images and explanations. If you try to negotiate a return or lower the rating after receiving the product because it is "different from what I expected," please purchase a new one at the regular price at a store. Thank you. ******************** Thank you for your understanding of long-term storage items. ★Please refrain from purchasing if you are nervous or particular★ Underwear for nursing care
