Jack & Friends Mini Neoprene Character Backpack for Kids (Shark)

I loved this backpack. We purchased it at the Long Beach Aquarium a few months ago. While the outside had held up beautifully, the inside has not. The material immediately began to fray and pull apart. Most of the interior of the backpack is now in strings and pulled apart. Super disappointing. My son barely wears it. I mostly carry it back and forth, so we are not rough with it in any way.
