I use them too, but in the bathroom for hair bands & such. Easy to grab & go when on the road. I also save & reuse the potato bowls from KFC. They are black with a clear lid. When I make chili, potato soup & stew, I always make a huge batch & fill several of these for the freezer. I then have one meal servings ready for the microwave. I can spend more time sewing instead of cooking. LOL
