I absolutely love these bags, and so do my girls. They have multiple colors each, and use them for their various needs; like snacks, small toys, and the occassional hairbrush. They are made with 100% cotton yarn. This allows the bag to hold its shape, even after washing. There are two different strap lengths, the shorter strap is for toddlers, however the longer strap can be adjusted by tying a knot to fit your child's desired length.
