It actually fits all my ornaments! I went from over 14 ornament original boxes and 3 storage containers to 1 box! Though when you have to take the ornaments out of next year you will basically take the whole box down, which is good but bad if your looking for one ornament in the middle layer. IF you have bigger ornaments, put them on the corners because those are bigger and can move to fit larger ornaments. I don't know about the durability because it is a kind of flimsy box so I just put it in an extra storage container just in case. I definitely suggest people get this product.
