Overheating can sometimes happen when parents are busy prepping food for their family - but they don't need to fear, Munchkin have their back against burned tongues during mealtime. When they pour food on these plates, the White Hot® strip will activate and turn bright white if it's too warm for consumption. The plates stack oh-so-neatly when they put them away at the end of the day, too. Mealtime burns be gone!
