Barbie and Stanley have collaborated in honor of Barbie’s 65th Anniversary with eight new Barbie-themed Stanley Quencher tumblers, but only limited quantities are available. Today’s drop includes the release of the Barbie x Stanley ‘70s Superstar and ‘80s Dynamite 40-ounce Quenchers now available for purchase.
