These are CHEER sarouel pants. There are small stains, as shown in photos 3 and 4, although they are not very noticeable. There is also some slight fuzzing. The tag has been cut off, so the size is unknown, but they were worn by someone who is 153cm tall and of average build, so I've listed them as S. The eye-catching color makes them suitable for various activities such as dance, aerobics, and yoga!
