Thank you for viewing! I am listing this on behalf of my family. These are Gunze thermal tights, size L ~ LL. The denier is unknown. It's difficult to tell in the photos, but the color is dark navy. There are no pills and no noticeable stains. Please forgive any oversights. Please understand that this is a used item, inspected by an amateur, and stored at home. Also, these were stored at my parents' house, where they have a cat, so please be aware if you have allergies! I removed any visible cat hair, but I didn't use a lint roller as it might damage the fabric. Therefore, some hair may remain in areas you can't see. Thank you for your understanding. If you have any questions, please feel free to comment.
