These are Uniqlo children's leggings. Sizes are 80 and 90. The beige ones have been worn very little and have no noticeable stains. The khaki ones have a stain that looks like oil, but it's not very noticeable. There are no holes, snags, or wear on the knees or the seat. There is some pilling from washing. These are used items worn by a child, so please understand that they are pre-owned.
