Cloth Swim Diapers (Set of 5) Size 6-12 months. These are in great shape, no stains. There is no size listed but I would say they fit anywhere from 6 to 12 months. I thought I could use them this year for potty training but they are too small for my 2 year old. They are blue but with pink prints, since I personally not care I used them with my son last summer. Shipped with USPS Priority Mail.
