Dungeness crabs 5.5 mm across the back. 16 crabs, unpainted. Note: These are the smallest crabs we can make currently and they are DIFFICULT to remove from the supports, but if you are very careful, it is possible. It is difficult to keep the claws on the crabs and they are tiny. They will get better as we improve the printing. 5.5 mm = 10 inches in 1:48 O scale. We need not discuss HO then. Always wear PPE when working with crabs this big.
