I purchased this item because I was told it was necessary for hospitalization, but I didn't end up needing to use it. I'm listing it for sale because it feels wasteful to throw it away. This is a size M undershirt made of 100% high-quality cotton with antibacterial and odor-resistant processing. - Size: M (87-95) - Material: 100% high-quality cotton - Processing: Antibacterial and odor-resistant - Made in Japan Thank you for looking.
