New from Thermos, the SIPP insulated food jar features a very cool push-button open & close function built into the leak-proof lid. This lets you easily open and close with one hand. Nice! The SIPP food jar has a 16-oz. capacity and features a full-width, wide-mouth opening, so it's easy to eat from and easy to fill and clean. It features Thermax double-wall, vacuum-insulated stainless steel construction for maximum temperature retention and maximum durability. 5.3" tall, 3.8" in diameter, dishwasher safe.
