Carter's durable underwear; a design identical to some of their pajamas. I wish I could tell you more about how long they will last but when I bought them for my son he wasn't interested in potty training yet, by that point he had outgrown them. UPDATE: 08/29/15 This laundry shrinks after several washes! I purchased this stamp at the same time as another stamp - this stamp has shrunk to about 2/3 the size of the original.
