What customers say
This tumbler earns high praise primarily for its unique, witty graphic design, making it a favorite gift for those who appreciate clever humor.

Know before you buy
The double-walled construction is designed to maintain your beverage's temperature for several hours. While it is highly effective for daily use, performance can vary based on the ambient temperature and how often the lid is removed.
To preserve the longevity of the printed design and the integrity of the vacuum seal, we recommend hand washing this tumbler with mild soap and warm water.
Yes, the 18 oz capacity and handle-free design allow it to fit comfortably in most standard-sized vehicle and furniture cup holders.
The lid is designed to be splash-resistant for everyday use. However, it is not intended to be fully leak-proof, so it is best to keep the tumbler upright when carrying it in a bag.
The tumbler is crafted from durable materials chosen for their ability to withstand daily wear while maintaining the quality of your drink's temperature.
