Yep, they're definitely on Santa's "naughty list"! Joker, Harley Quinn, and Catwoman light up this fun 11-ounce ceramic DC Comics Justice League Batman Naughty List Morphing Mug that transforms from black to vivid full-color as a hot liquid is added. Watch as the heat-activated process reveals the hidden image and brings it to life! Do not microwave. Hand wash only. Not dishwasher safe.
Even Gotham has its very own naughty list during the holidays, and Joker, Harley Quinn, and Catwoman like to make sure they stay at the very top. Featuring adorable versions of some of Batman's most well-known villains, this Morphing Mug is a great gift for both young and old alike. Ages 13 and up.
