The OXO Good Grips POP Container is the next generation in air tight containers. It is slimmer in design than its predecessor. One of the notable added feature is a small notch under the lid. While the notch may seem insignificant, it is actually designed for the OXO measurement scooper. The 1.1 QT / 1L is the perfect size for 1lb of dry goods such as sugar, rice, flour, tea, or any other powder goods. I put some crackers in it. The container is BPA free. You can shop for accessories that pair well with the POP containers on the OXO site that fit lid size C. Using this container is the same as before. Just press the round button on top of the lid to open and to close. The button doubles as a handle for the lid only. Container itself is dishwasher safe and the lid can be disassembled for cleaning.
