Yes and Yes. Extra MugTops are available as an add-on. They are available as add-ons on the main shop screen or on the cart page. You can select any colour. It doesn't have to be the same as your full BOLT heated travel mug.
Each of the Bolt Smart Mug MugTops is completely interchangeable, dishwasher safe and will work on any base.
That means you can combine colours and style your Bolt rechargeable heated coffee mug any way you want!
