Unused, washed only. Although purchased from different sources, both are size L. The white one is labeled as 100% cotton. I dislike slippery innerwear, so I believe the black one is also cotton, or a fabric with a high cotton content. More photos are available from the 7th image onwards. Can be bundled at a discount with other women's clothing! #KioBundleSale You can search for other items from the above hashtag.
