Best way to organize dice?

Hi, my mother is a dice goblin. She is looking for a way to organize all her dice in some sort of box(?) or bag. The issue is though that she doesn’t want to take her dice out of the original small tins or boxes they came in because she likes to keep them all separate from each other. I have suggested dice bags, tackle boxes, etc etc. Does anyone have any suggestions on how to organize them while keeping the original dice containers intact? Any advice is greatly appreciated!!
