Cowabunga, dude — 42 years of shell-kicking excellence! This TMNT 42nd Anniversary Retro Tumbler celebrates four decades of Leonardo, Donatello, Raphael, and Michelangelo saving New York City in the most radical fashion possible. Bold retro cartoon artwork for fans who grew up in the sewer and on the Saturday morning couch. Keeps drinks cold forever — or at least until the next Foot Clan attack.
