Does the warmer plate stay safe?

The heating base maintains a gentle constant temperature while your mug rests on it. It is designed for steady desk warmth and features built-in thermal protection to keep your drink cozy without scorching.

Can I use other mugs with it?

While the set includes a custom flat-bottom ceramic mug for optimal heat transfer, the warmer base also works with most standard flat-bottom glass, ceramic, and metal drinkware.

How do I clean the base plate?

Simply unplug the warmer and let it cool completely, then wipe the smooth tempered heating surface with a damp cloth. Never submerge the electric base in water.

Is the set packaged for gifting?

Yes. The set arrives in a festive presentation box containing the ceramic Grinch mug, fitted lid, electric warmer base, and gold spoon, ready for holiday gifting.
