Review on Multipurpose Stainless Steel Mixing Bowls Set with Lids - Stackable, Space-Saving Design, Non-Slip Silicone Base - 1.7/3/4.7 Quart by Henry Hunter

Great mixing bowls. The light and rubber on the bottom prevent them from moving during use. I had to buy a silicone mustache to protect the shells from scratches, but I ended up liking it better than the metal one, so he would keep using it even if I ended up getting rid of the shells. The lids come in very handy, especially if you have to leave something in the bowl for a long time, but be careful as they don't close at the top and can pop out easily.
