Tupperware Fridgesmart 4 Piece Food Storage Container Set, Dishwasher Safe and BPA Free (4 Containers, 4 Lids)

Tupperware's unique ACE system: Fresh for the long haul. Our proprietary Atmosphere Controlled Environment system regulates airflow and humidity inside your FridgeSmart container to extend shelf life. Adjustable airflow slider: Three venting positions that optimize air circulation through the Tupperware FridgeSmart container depending on the type of produce you’re storing, so your cherries stay crisp and your carrots stay crunchy. Venting guide: This illustration on the face of your FridgeSmart helps you quickly decide which venting position is right for the produce you're storing. Ridged bottom for drier produce: The ridged bottom of the FridgeSmart separates your food from condensation as it collects-creating a drier environment for longer-lasting produce. Modular design magic: Tupperware FridgeSmarts stack without covering the vents of the containers below-helping you better organize fridge space without blocking airflow.
