We had a set of colored plastic chopping mats awhile back. Each color represented a food group and was supposed to prevent cross-contamination of food. Eventually the chopping mats got all chopped up and I haven't replaced them. I always wondered that since I stored them all next to one another that the cross-contamination prevention was a mute point. I would have had to have another plastic sheet separating them. This product solves the problem. You just need to find room to store the filing unit. Pretty cute.
