Common extras include measurement markings on containers, terra cotta freshness disks, scoops or levelers, and magnetic accessories that attach to lids—in addition to the basic containers and lids.
Common closures include airtight, leak-proof lids with secure latches (some use two-latch designs) and silicone or locking seals that create an airtight fit to preserve freshness.
Designs often feature stackable or modular shapes that nest together to maximize cabinet, pantry, and refrigerator space while keeping ingredients organized.
