These are fleece pajamas. Personally, I think they're warmer and the fabric is more substantial than UNIQLO's fleece pajamas. Some slight pilling is visible. There is a small stain on the back of the right hand. See image 3. There are some stains on the pants. Image 4...front Image 5...back. Personally, I don't think the stains are as noticeable as they appear in the images. Please leave the shipping method up to me.
