Stainless Steel Vacuum Car Ice Master Tumbler
Material: 304/201 stainless steel
Size: 30OZ / 20OZ
The tumbler is a great size and keeps drinks cold. I put some ice cubes in my tumbler and while some of the ice had melted overnight, there was still a chunk of ice the next morning.
Very, Very Happy With My Purchase
When you take the top off you’ll want to open it with a twisting and pulling motion rather than just yanking directly up. It is a very tight seal, but will be so worth it when you accidentally drop or knock over this cup (everyone does at least once).
All Around Quality
The materials are solid. I like the outside texture compared to some competitors that have a smooth surface that I feel could slip out of my hands, if wet.
The full reusable cup package!
Product came exactly as described! I really like it. would definitely recommend
Love the flip-top lid
I didn't test how leak proof it is but I can tell you it seals well. I tried to remove the top without opening the flip top lid and the vacuum was so great that it wouldn't come off. The only way to remove it is to open the flip top to break the vacuum first. That tells me it seals tight.
