A great collection, I had used KiwiCobin the past for the younger line up and the products seemed of lesser quality and we're pretty boring. This crate was fantastic. I have an 11 year old being an 11 year old who wants to just be on her phone and play roblox, not with this crate she got it herself and put the headphones together without me ever asking her to. She loves the little lockbox for herself and gave the pencil sharpener to her math teacher!
