Frequently Questions

How does the Leak Proof Coffee Cup ensure no leaks?

Our Leak Proof Coffee Cup uses a multi-layered sealing system that includes a precision-engineered silicone gasket and a pressure-locking lid. The lid creates an airtight seal that prevents any liquid from escaping, even when the cup is turned upside down or shaken. We test each cup with water under pressure to ensure zero leakage. The gasket is replaceable, allowing you to maintain the seal over time.

Can I put the Leak Proof Coffee Cup in the dishwasher?

Yes, our Leak Proof Coffee Cup is dishwasher safe. The stainless steel body and lid are designed to withstand high temperatures and detergents. However, for the best longevity, we recommend hand washing the lid to preserve the gasket’s elasticity. The cup’s exterior is also resistant to fading and scratches, ensuring it maintains its aesthetic appeal.
