MATURE- I swear like a sailor people-- and this item features the "F" word in all its gloriousness. Do MERMAIDS complain about Monday? NO. They're up early outswimming the sharks, being beachy, beautiful and badass, reminding everyone they're a fucking mermaid. Grab life by the tail with this travel mug that reminds you that girls just wanna have fins. This is a double walled stoneware ceramic travel mug created by me in my New Jersey studio. This tumbler measures 3.5 x 6 and ships with a hard plastic lid that has an open and close feature. The double wall insulates your beverage--keeping hot liquids hot and cold liquids cold. Holds 16 oz.
