Frequently Asked Questions
Are these tumblers truly leakproof for carrying in a bag?
These KISSKIND tumblers use a rotatable hidden-straw lid designed to reduce leaks and protect the straw when closed. Many teachers report good leak resistance in daily use, but some users have found occasional leaks around straw connections or experienced lid/handle wear after heavy use; inspect seals regularly and avoid tossing the cup into a bag with the lid loose.
Can I put the tumbler and lid in the dishwasher?
Manufacturer features state both the tumbler and lid are dishwasher safe. For long-term seal and lid life, many teachers recommend placing lids on the top rack and occasionally hand-cleaning or drying silicone gaskets to prevent wear and trapped moisture.
How do I clean the straw and hidden lid parts?
Use the included stainless steel straw and clean it with a narrow brush or in the dishwasher if the product info allows. Remove any silicone seals from the lid and rinse or run through the dishwasher; check for trapped debris at the straw connection and replace seals or small parts if you notice persistent leaks.
