Need shells for blue legged crabs

[POLARBEAR0871]

Is there anyway I could make shells of different sizes for my dwarf blue legged crabs I have ten of different sizes and they're growing very fast

You can buy them off ebay. I brought a pack of 20 shells for my blue leggers & they didn't cost that much either.
