>>11180624I have actually seen people get custom cases like that but they are very expensive for storing toys. I assume there is a cheaper somewhat elegant solution I haven't been looking super hard as I don't have a big enough collection yet I've seen reasonably nice similar cases with foam squares for carrying 100+ Warhammer figures for like $20-25, cheaper ones for storing circular things like bottles, paints, essential oils etc so if you find a product that's a similar size you could snag a good deal on something that looks nice. If you don't wanna take a knife or hot wire to your foam there is pick and pluck foam which is for like tools and big stuff that are awkward shapes, might not be ideal for beys as it's made up of squares but if you find one that is the perfect size you could make something tidy.
I'm probably just going to go with a big plastic container with individual squares in it. It seems like the most popular options besides chucking them in the stadium or a shoebox all together
