These are Cloudtouch yoga pants with a heel loop. They have been used a few times and are a used item. There are no bad odors or stains, but they were stored in a chest of drawers with mothballs for a while, so they have a slight floral scent of mothballs. Please be aware of this if you are sensitive to smells. There are no pets or smokers in my home. If you purchase these items along with other items I have listed, please leave a comment before purchasing, and I will discount the shipping cost for combined shipping.
