We've partnered with our friends at 3dretro.com on a line of Back to the Future Geeki Tikis® based on the 1985 sci-fi classic. The set of three includes our tiki-fied take on Marty McFly, Doc Brown and Einstein the dog. Limited to just 1000 sets, each Geeki Tikis® mug features beautiful sculpted detailing true to the character it is paying homage to. These ceramic mugs are high-quality, and microwave safe. We recommend hand-wash only. Experience the aloha with every sip!
