this is a toolbox, that is perfect for office organization. the side compartments can be used to store very small items, like USBs, push pins, tacks, paper clips, and more! the big section in the middle can also be used to hold Airpods. I've tested this with the 1st and 3rd generation models. feel free to try it on other types of models, and make sure to take off the protective case, and keep it in the case that it came in. dm me if you have further questions!
