Review on Space-Saving Set of 4 Double Wall Stainless Steel Mixing Bowls with Airtight Lids - Non-Slip Bottoms for Stability - Ideal for Cooking, Baking & Food Storage by Smiley Edwards

I love these non-slip, plastic-coated aluminum bowls with lids. They are easy to handle but easy to grasp and use. I realized they couldn't be used in the oven or in a pot of hot water, but neither could my old plastic bottles. These are colorful and fun. Four stars because I wonder if the plastic liner will eventually let water through between it and the metal shell. So far they seem to be completely tight.
