Officially licensed and perfect for fans of Naruto, this mug and coaster set makes a wonderful gift! Just like the shinobi of Konohagakure's Ninja Academy, this heat-activated magic mug has mastered the clone jutsu technique. Fill it with the hot beverage of your choice and watch as its walls heat up and the image on them transforms to show you Naruto's clone jutsu in action. And because a true ninja's best weapon is stealth, we've included a coaster featuring the Konoha symbol to prevent tell-tale rings on surfaces from letting the Akatsuki know where you've been.
