I recently discovered this awesome product. If you are storing home-made ice cream or transporting your favorite store bought brand, this insulated ice cream keeper is a must. I cannot tell you how many times I have brought ice cream home from the store only to find ice cream soup. The Zak ice cream Tubbie fits a pint of ice cream from the store so that you can keep it cold on your way home. It is also great for packing cold salads to either take for lunch to your office or a party as well as holding homemade ice cream. This ice cream keeper (made by Zak) is fully insulated with a freezable gel lid to keep contents cold for up to 90 minutes. The 1 pint container measures 5x5x5 ½ inches. These ice cream keepers come in a variety of fun colors and are freezer and dishwasher safe, but NOT microwavable. The seal on the top seems to get quite tight and can be difficult to get off (which can be annoying) right after the container leaves the freezer, but within a few minutes it thaws enough to remove easily or you can run it under warm water for a moment. The cost is from $16 to $25 per Tubbie and can be purchased at either Amazon or the Zak Designs website.
