0396 – Ultra•Seal™ 4 Piece Bowl Set Sterilite’s Ultra•Seal™ 4 Piece Bowl Set brings together two popular-sized bowls, 4.7- and 8.1-quarts, into one value-oriented set. Each bowl includes four latches and a silicone gasket that creates an airtight and watertight seal to keep food fresh longer. Both sizes are great for storing, serving and transporting salads, snacks and desserts. When not in use, Ultra•Seal™ bowls store efficiently inside of each other to use less space in the cupboards.
