Buzzman, Burger King Cook Up Drinkware

has partnered with

Buzzman

on a line of flame-grilled glass cups available in France.

For a limited time, the fast food chain is offering a cup for free with every Bacon and Cheese Whopper purchased in France.

Buzzman and Burger King have produced more than one-and-a-half million of the glasses in partnership with tableware maker

ARC

. ARC’s production process makes every cup slightly different, with some glasses looking more grilled than others.

The deal with Buzzman marks another crossover for Burger King. Last year, the chain

partnered with Emoji

for a branded meal agreement for its Brazilian restaurant locations.
