These are Uniqlo fleece leggings. They appear to be in good condition with almost no wear or stains on the knees or seat, but please check the images before purchasing. *Please refrain from purchasing if you are looking for a perfect item, as it is not completely free of imperfections. We wore these for indoor outings like shopping malls, but they are also perfect for parks or daycare. There are no noticeable stains, but there may be oversights due to my amateur inspection. Please refrain from purchasing if you are sensitive to such details. Thank you for looking. I have many other baby clothes for sale. Please take a look.
