The famous 7-Eleven slurpee is getting a makeover. The recipe isn't changing but the cups are as the company wants to ditch its psychedelic pinwheel look. The cup has had seven redesigns since 1966. The new design will feature a new logo and the "S" on the cup will resemble the swirly top of the drinks. The revamp is inline with the company’s latest campaign, "Anything Flows" which features “eccentric colors and eclectic vibes” paired with a new logo of a large "S.” According to the National Association of Convenience Stores, 7-Eleven is the largest U.S. convenience store chain.
