Adjustable and collapsible, this may be the most versatile colander around. It measures 10.5" x 15.5", but the arms extend up to 24", so it can rest securely on most sinks. It has a capacity of 6 qts. and a drain hole pattern that allows water to drain quickly. Sturdy enough to stand on its own, it folds down for storage, so that it's less than 2" tall.
