- Do the seals make these tumblers leakproof?
- The round seals are designed to close the tumbler for travel and storage. They work best when pressed down evenly all the way around; a partly seated seal can let liquid escape.
- Are these tumblers insulated?
- No. They are single-wall plastic, so they don't keep drinks hot or cold for long. They are light and easy to carry rather than temperature-holding.
- Can they go in the dishwasher?
- Tupperware plastic tumblers are generally washed on the top rack, and the seals are best hand-washed to keep them flexible. Check the care instructions that come with the set.
- What can I use 12-oz tumblers for?
- They fit a standard glass of water, juice or milk, and the seal makes them handy for lunch bags, kids' drinks and short trips. They also work for storing small leftovers in the fridge.
- How do these compare with an insulated travel tumbler?
- An insulated stainless tumbler keeps drinks cold for hours but is heavier and costs more. These are lighter, nest for storage and seal with a simple round lid, but they don't hold temperature.
