Product description ------------------- Thanks to Tupperware's ingenious ACE (Atmosphere Controlled Environment) system, the three containers in this set keep produce fresher in the refrigerator. Because fruits and vegetables "breathe" and require varying as of air each container has two vents. The containers' bottoms also have raised grids to elevate produce above its own moisture and prevent spoilage. The vents open and shut with the touch of a finger. High-rate breathers like artichokes and spinach need both vents open. Medium-rate breathers like cabbage and citrus require one open vent. Low-rate breathers like asparagus and berries stay prime with both vents closed. (A chart of various items' needs is included.) The rugged plastic containers are also terrific for ripening tomatoes, apples, pears, and bananas on the counter. The set consists of a rectangular 19-1/2-cup container (14-3/4 inches long, 4-3/4 inches wide, 5 inches high), a rectangular 7-cup container (8-3/4 inches long, 5-3/4 inches wide, 3-1/2 inches high), and a square 4-1/2-cup container (5-3/4 inches square, 3-1/4 inches high). They fit together compactly, have textured seals to resist sliding when stacked, and are translucent so contents can be identified. Virtually unbreakable and dishwasher-safe, Tupperware carries a lifetime warranty against chipping, cracking, breaking, and peeling .com ---- Thanks to Tupperware's ingenious ACE (Atmosphere Controlled Environment) system, the three containers in this set keep produce fresher in the refrigerator.
