- Is this tumbler really microwave safe?
- Yes. The polypropylene body and double-wall build are stated as microwave safe, so you can reheat a drink in the cup. Leave the lid off while heating.
- How long does it keep drinks hot?
- The double wall slows heat loss and stops condensation on the outside, but it is not vacuum insulated. Expect drinks to stay warm for a short while, not hours like a stainless vacuum mug.
- Does the lid leak?
- It is a screw-off sipper lid, which resists splashes better than a plain open rim. It is not a sealed travel lid, so carry it upright in a bag.
- Can I put it in the dishwasher?
- Hand washing is the safer choice for the plastic body and lid. If you use a dishwasher, keep it off the heated drying cycle.
- What is it best used for?
- Coffee, tea and cold drinks at a desk or around the house, and bulk orders for events or branding. For all-day heat on a commute, a vacuum-insulated tumbler is the better pick.
