Stanley Everyday Camp Mug - 350ml - Black

No, the lid is a press-fit design intended for easy sipping and splash prevention. It is not designed to be completely leak-proof, so avoid storing the mug upside down or in a bag where it could be subjected to significant pressure.

The 'Built For Life' promise is Stanley's commitment to manufacturing high-performance products that last a lifetime under normal use. It signifies the durability and quality of their products.

Stanley does not recommend putting vacuum-insulated products in the freezer, as it can potentially damage the vacuum seal and affect performance.

The lid is made from Tritan™, a durable and BPA-free plastic.

Stanley's finishes are generally durable. However, like most coated products, it can be susceptible to scratching or chipping if subjected to harsh treatment or abrasive cleaning.

The 350ml capacity refers to the volume of liquid the mug can hold up to the brim, not including the space taken by the lid.

Ensure the press-fit lid is securely in place. Check for any damage to the lid or mug that might compromise the seal. For best results, pre-heat or pre-chill the mug with hot or cold water for a few minutes before filling with your beverage.

All parts of the mug are dishwasher safe and should be placed on the top rack. If hand washing, use warm, soapy water and a soft brush or sponge. Stubborn stains can sometimes be removed with a mixture of baking soda and water.

Ensure the mug rim and the lid seal are clean. Sometimes a slight twist while applying pressure can help. If it's consistently too tight, check for any defects in the lid or mug rim.
