Another Tupperware Classic and one of the biggest favorites of all time. The tapered design is easier for smaller hands to hold. These tumblers stack for space-saving storage. They each hold 7-oz. of liquid and come in colors Lime/Orange Peel/Fuschia Kiss/Tropical Water. Use them with the Sipper SealŪ Set (included) to help toddlers learn to drink from a tumbler. The sipper seals are virtually liquid-tight seals to eliminate messy spills. Both these Tumblers and the Sipper SealŪ Set are recommended for children 6 months and up. The snack cup seal also fits these tumblers. Dishwasher safe.
