I am a hot wheels collector for 2-3 years now. These cases are perfect for being on the wall. By this, I mean that if you nail a bracket to the wall or something similar, you can hang the case with the cars inside. Each individual box can fit the average-sized cars, but it doesn't have much height (which is understandable) and makes it a bit difficult for pick up trucks and SUVs. Apart from that, for collectors, the set is just what you need since it is affordable and quite convenient.

Unfortunately, the boxes do not close and open easily, resulting in my 5.5 and 4-year-old children constantly asking for my help. Even I struggle to open and close it.

First of all, it only supports flat models, not all models.... The connectors are not sturdy enough and I doubt if it will hold on the wall when I hang it, I am hesitant.
