Frequently Asked Questions

Q: Will this 40oz replacement lid fit my Stanley or other brand tumbler?

A: This lid is designed to fit 40oz cups with a 10cm (approx. 3.94 inch) diameter opening. Before purchasing, please measure your cup's opening diameter carefully. It is not guaranteed to fit all brands — always verify the size first.

Q: Is this lid completely leakproof when used in a car or bag?

A: Yes! The snap-lock flip cover and the silicone-sealed straw hole work together to create an airtight, leakproof seal. Whether the cup is in your car cupholder or tossed in your bag, drinks stay inside where they belong.

Q: Is the plastic material safe for hot beverages like coffee?

A: The lid is made from BPA-free, food-safe plastic. It is designed to handle both hot and cold beverages. For extremely hot liquids, allow your drink to cool slightly before sealing to maintain optimal lid performance and longevity.
