Your perfect warmth — extended. Keep your Ember Mug splash-free, while extending the battery life to keep your drink warmer for longer, designed specifically for our first and second generation 10 oz coffee cups.

• Compatible with 1st and 2nd Generation Ember Mugs in 10 oz size

• Fits securely onto your Ember Mug using a silicone gasket -- simply push on or pull off

• Easy-to-Use Lid for Ember Mug: To add the Sliding Lid to Ember coffee mugs, simply press the Sliding Lid onto your temperature control mug until the silicone ring is no longer exposed

• Easy to Clean: Remove the sliding lid from your heated coffee mug; We recommend removing the silicone band from the bottom rim of the Sliding Lid so you can wash both separately, as well as periodically removing the slider to clean underneath
