As a tip in using your tumbler, always remember that heat expands! Please allow the contents in your tumbler to cool for 1-3 minutes before tightening the lid to prevent the mouth piece from opening due to pressure. Never shake or turn your tumbler upside-down, if contents are hot. The pressure that hot water creates will cause the top to potentially open, spilling the contents. Once the tea is cool it becomes safe to turn upside down.
Note: We do not recommend that you pour boiling water directly into your tumbler - if the water comes to a boil please allow the water to rest for a few minutes before pouring into your beautiful tumbler!
