IMPORTANT NOTES
Your insulated drink bottle is only leak-proof when the flip lid is shut, the straw itself is not leak-proof. So, it will leak if the lid is left open and the bottle is tipped on an angle or upside down.
If it seems to be leaking when the flip lid is shut, try closing the lid slowly so you can ensure the groove inside the lid is matching up with the straw. Always make sure the straw top is pulled through all the way until it ‘clicks’ into place, and that the straw disk that sits under the lid is firmly pressed in place.
