This is for Slim Feather leggings. I purchased multiple pairs, opened them to check the contents, and am now selling them as I didn't use them. Similar products may be circulating, but please confirm that these are genuine by checking the tags in the photos. Please check the size and other details before considering a purchase. Although these are unused, they have been stored at home, so please refrain from purchasing if you are concerned about initial scratches, etc. I have multiple pairs, so I can offer them as a set. I also have the cool type available, so please comment if you're interested. Returns are not accepted. Thank you for your understanding. These black leggings are made of 90% nylon and 10% polyurethane, and are expected to provide compression effects.
