Pirani Tumbler FAQs

The Pirani Party Tumbler can hold 16 fl oz (473 mL) 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.

Best Cups

These are the best cups! They float and keep your beverages cold. They stack for minimizing storage. AND they come in great colors!

Great for tropical vacation

Love this cup! The only reason I did not give it 5 stars is because when the cup is almost empty, it flips over in the water when floating.

It keeps drinks very cold in warm climate and warm water. It had full ice cubes when I went to refill. Great for my tropical vacation!
