The BOLT smart heating bases and MugTops are designed to be completely interchangeable.
The bayonet mounting system allows you to easily click on and click off any MugTop with any base of any colour.
Almost all of our customers buy multiple extra MugTops to use with their smart bases while their other MugTops are in the dishwasher.
On the shop page, there are add on buttons to purchase additional MugTops in any colour.
