Most are made from plastics—commonly polypropylene. Other materials in this group include vinyl, polyurethane, woven fabrics, and EVA-based soft plastics used for some tote bags.
Capacities observed range roughly from 18 quarts up to 72 quarts. There are also gallon-size tubs in this set (for example, 20‑gallon and 27‑gallon models), plus mid- and large-size options like 32‑quart and 66‑quart.
Common styles include snap-closure and latching lids. Many bins also feature click-lock or locking handles and recessed or stackable lids designed to secure contents.
Many items are designed to stack: recessed or hi‑rise lids let bins sit securely one on top of another. Some sizes explicitly share lids, so shallow and deep bins can stack within the same footprint.
Several bins use clear or transparent bases and lids so you can see contents easily. Other models use opaque or solid-color lids and bodies, depending on the style.
