This baby backpack comes with a harness to prevent children from getting lost or running off. The cute bee design makes it easy for children to wear without resistance. The strap can be removed to make it a regular backpack. It helps prevent children from getting lost and prevents accidents. It's about the right size for about two diapers♪ It's also convenient for storing snacks and treats. There is a brown stain inside the backpack (see photo 7). The brown stain is not visible from the outside, so it seems to be okay in appearance, but please be aware of this. Photos 4-7 are photos of the actual product. Instant purchase is OK.
