Our tumblers feature threaded, twist-on lids for a secure seal. They’re ideal for carbonated drinks, hot coffee, and tea. All OneFIT lids are interchangeable across all Pirani sizes. Not compatible with OG press-in tumblers or lids.
The Pirani Party Tumbler can hold () of your preference.
Keeps drinks ice cold or piping hot for hours!
Ombre patterns are handwash recommended to keep the colors bright! All solids and textured patterns are dishwasher safe.
While floating isn’t one of the main features of our tumblers, our 16oz and 26oz sizes do float! Just make sure the air-tight lid is securely on and the tumbler is filled about 2/3 to 3/4 full.

Marcello Pirani was a German physicist that invented a vacuum gauge, which is one of the main tools used during manufacturing of the Pirani Party Tumbler.
Works as described, can turn it upside down and it doesn’t leak! Also keeps coffee hot. Went to the gym, when I came out, my leftover black coffee was still hot. ❤️
I ordered the 16 ounce to take with me on a cruise so I could have hot coffee and it all day and I used it every day and loved it! It does not leak it wipes clean easily and the print is absolutely beautiful.
These cups are always great and never dissapoint? Converted me from a long time YETI user, just as cold and you can stack them taking up much less cabinet space.
This cup is better that I thought it would be. I Love the color and its very sturdy and I take it everywhere. Hols a good amount of liqud at once and stays afloat in the pool. I will be buying more in the futre for sure!
Got as gifts. Everyone lived them
