Vintage Merco Medical Glass Apothecary Storage Jars Stainless Lids Set of 3

One lid has two rusty spots that could maybe be cleaned off with the right product. I’ve been using these in my bathroom cabinet for years for cotton pads, q-tips and cotton balls. The canisters themselves are in great condition with no chips or cracks. I believe they came in a set of four originally (maybe more). Got them at a flea market about 10 years ago.
