The collapsible strainer expands to a two court capacity with a simple flick of the wrist. The unique design allows it to collapse down to a mere one inch (the thickness of a dinner plate). When collapsed, it takes up to 80 percent less space in a dishwasher than a comparable sized standard strainer. When it is flattened, the surfaces and holes remain exposed for optimal cleaning. Withstands heat up to 250-degree.
