Although the Pirani Party Tumbler is extremely durable, it does not like dishwashers. You should NOT put it through the dishwasher or soak in hot water.
The dishwasher can get hot enough to affect the insulation and affect the powder coat. Soaking in hot water can also discolor the powder coat.
The double wall vacuum insulation will protect the liquid inside of your Pirani Party Tumbler and will not freeze. The best way to get you drinks the coldest possible temperature- put some ice cubes inside and notice they will still be there at the end of the party!
Mid way through the campaign you will find a custom bag design add-on for your larger party packs to transport your Pirani Party Tumblers in style! It will be made from recycled materials to stay in line with our mission and will be manufactured in a facility that is socially and environmentally responsible.
