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.

After years of going bad before their time, your fruits and veggies deserve to breathe a little easier. Meet the Tupperware FridgeSmart containers. Developed with top food scientists from the University of Florida, the container’s ACE (Atmosphere Controlled Environment) system balances the flow of oxygen and carbon dioxide to match the “breathing” needs of the specific foods you’re storing—all while controlling moisture, too. It's like flipping the script to finally give your cucumbers (and kale, and cranberries, and the rest of the fruit and veggie crew) the royal spa treatment, so they'll feel—and taste—fresh for up to three whole weeks.* *Duration depends on type of produce
