Tumbler Buddy is compatible with any standard size20ozTumbler!

 Tumbler Buddy allows your 20oz Tumbler to act as a beverage insulator to hold 12oz Cans/Skinny Cans/Bottles/Stubby Bottles and 16oz cans.

 What comes with the Tumbler Buddy is the Tumbler converter insert and the Tumbler compression top lid!

Tumbler Buddy allows your drinks to stay as cold as the ice you normally would place in your Tumbler. 12+ hours! You now don’t have to worry about your drinks getting warm, or watered down due to the ice cubes!

We recommend to keep the Tumbler Buddy in the freezer for at least 2 hours prior to use to turn the freeze gel frozen solid, however it will still help keep your drinks cold due to the tumblers double insulated walls it is placed in without adding to the freezer.
