Most listings show colanders made from plastic/polypropylene (including recycled polypropylene) and stainless steel. Several product descriptions explicitly list these materials.
Capacities range from very small to multi-quart/liter options. Examples in the results include 2.5 ounces, 9.75 ounces, 41.45 ounces, 3.08 liters, 3 quarts, 3.7 quarts, and 5 quarts.
Options include large-hole/plastic drain designs, drain holes located at the base, generously spaced holes for fast drainage, and fine-mesh strainers for finer filtering—so both coarse-drain and fine-mesh choices are represented.
Some mesh strainer sets come as three nested, fine-mesh sizes. Example size callouts include head diameters of 3 1/8 inches, 5 1/2 inches, and 7 7/8 inches.
Listings describe long or top handles that allow a colander to rest on pots, integrated side handles or dual side handles for carrying, and handles designed to provide a secure, comfortable grip.
Designs include top frames or handles that let the colander rest on pots, feet or bases so they stand on the counter, and expandable or over-the-sink models that fit across the sink for draining.
