Cork Bottom 18 oz Vacuum-Sealed Mug - 24hr Cold Retention

Carole Tremblay Verified Buyer 03/30/26

Temperature control actually works

Tested the insulation performance and it's impressive—24-hour cold retention is real. The cork bottom provides stability and a premium feel. The clear spill-proof lid is convenient. Laser engrave imprinting created a crisp, permanent logo. Rachel coordinated smooth delivery.

Premium insulation, elegant design

The 18oz size is perfect—not too large, not too small. Copper-lining keeps beverages at ideal temperatures longer than standard tumblers. The cork bottom adds sophistication and stability. Our laser-engraved logo looks professional and permanent. Customers receive this as a valued gift.

Great Quality But Minor Issue

The mug itself is beautiful and well-made. After a few months of use, I noticed the cork bottom becoming slightly uneven, but it doesn't affect the functionality. The vacuum seal is still perfect and keeps my drinks at temperature all day.

Exceeded All Expectations

Robin was fantastic throughout the entire ordering process. The vacuum seal works incredibly well - my coffee stayed hot for nearly 12 hours! The eco-friendly packaging was a nice bonus. The powder coating feels premium and durable.

Sustainable and Stylish

I appreciate that they've eliminated single-use plastics in the packaging. The mug's performance is outstanding - keeps ice frozen all day. Angela was extremely helpful in getting our artwork positioned perfectly for the laser engraving.
