The mug comes with a push-on, splash-proof lid to trap in the heat. Just ensure that you don't turn a filled travel mug upside down to avoid likely leakages. You can enjoy your drink through the sliding door at the top.
This mug comes with built-in cork bottom to prevent scratching and staining on the wood desk or glass table. It is a great choice for the office or home use. The cork bottom allows you to place the mug on any tabletops without a coaster.
