Heat Sensitive Warm Heart Mug Fills Up As You Fill it Up With a Hot Drink
Heat sensitive mugs can come in many forms, but not all quite as charming as this. This is a heat-sensitive mug that comes with a big red heart on it.
The Warm Heart mug comes with a big red heart, in a nostalgic 8-bit form that has the ability to change its capacity depending on level of hot liquid filled in it. When you fill it up with a hot drink, the heart will fill up with a happy red color, but if you leave it alone for too long it loses its color as your drink cools down.
A nice mug that will surely bring a smile to a loved one in the mornings. One that should bring a smile to someone when given a big red heart on a mug with a delicious hot drink.
The heat-sensitive warm heart mug retails for $11 from Brando Gadgets.
