This is a 30oz. stainless steel vacuumed sealed tumbler that will keep your drinks hot for a very long time, and ice cold all day. I put ice in mine before work in the morning, will refill my water multiple times through out the day, and will still have that same ice left late at night. Cup comes with a sliding closure lid and can also fit a straw in it. All tumblers are sealed with food grade safe epoxy.
**PLEASE READ**- Tumblers are to be HAND WASH ONLY!!! They are not microwave or dishwasher safe. If they are dropped or hit really hard against something, the epoxy will crack and will not be able to be fixed.
