This particular package comes with a lot of them in a variety of sizes
Otherwise, though on the pricy side, I like these
She was using one of these bands to lower and raise a pan or bowl into and out of the cooker for pies, casseroles and so forth
I saw these on a site for pressure cooker recipes
They are not as sturdy as I had expected
I tried this myself and am pleasantly surprised that they really work for this purpose
