Contigo Byron Travel Mug 720ml - Gunmetal

Yes, it is designed to be leak-proof when the lid is in the closed position, thanks to the SNAPSEAL™ technology.

The lid is top-rack dishwasher safe. The body should be hand washed with warm, soapy water. Avoid using abrasive cleaners.

No, the Contigo Byron Travel Mug is not microwave safe.

The mug keeps drinks hot for up to 6 hours and cold for up to 12 hours, depending on the starting temperature of the beverage and external conditions.

The mug is made of double-wall, vacuum-insulated 18/8 stainless steel, and the lid is made of BPA-free materials.

It is designed to fit in most car cup holders, but it's always a good idea to check the dimensions against your car's cup holder.

The Gunmetal version is 720 ml.

Ensure the lid is properly sealed by pushing the lever down completely. Check the silicone seal within the lid for any damage or debris, and clean if necessary.

Pre-heat or pre-chill the mug by filling it with hot or cold water for a few minutes before adding your beverage. Make sure the lid is securely closed.

Clean the lid thoroughly, ensuring no residue is blocking the mechanism. Apply a small amount of food-grade silicone lubricant to the moving parts if needed. If it's still difficult, consider replacing the lid.

Fill the mug with a solution of baking soda and warm water, let it sit for a few hours, then rinse thoroughly.
