Smiley Heat Change Mug

Start your day with a big smile with this black & yellow Smiley magic heat sensitive mug.

Amaze your kettle. Watch this mug magically transform in front of your eyes as you pour in the hot water. From boring black to lively smile as you make your hot brew. Then gradually transforms back to boring as your beverage cools.

A perfect gift for anyone who needs a little help tuning in with a bright new day, or friends who appreciate happiness!
