The most common offering is a 10-piece set (containers plus lids). Other listings include single canisters and smaller multi-piece arrangements, but 10-piece sets appear frequently across product results.
Look for airtight, leak-proof seals and stackable, modular shapes for transport and efficient storage. Other useful features include microwave vents for reheating, freezer and dishwasher compatibility, and materials or finishes that resist staining and odors.
Many containers use clear materials (glass or transparent plastic) so contents are easy to see. Product descriptions and reviews also commonly note stain- and odor-resistant materials or treatments for lids and bases.
Most container bases are glass or plastic. Lids are commonly plastic, with some options in wood or glass. Some plastics are specified as BPA-free (for example, Tritan).
