This is an inner garment made of 100% cotton, stretchy material. I received it as a set from my mother, but I don't wear high-neck items much, so I'm selling it. It's unopened. I think this innerwear will be useful in the coming cold season. *Photos 4 and 5 are of the product I use and are not the item being sold. They are included for reference. Color: Black系 (Black-based) Season: Winter Condition: No stains, tears, or odors.
