Ahead of his matches at the U.S. Open, Novak Djokovic—winner of 16 Grand Slam singles titles and ranked No. 1 in the world in men’s singles tennis—spent some time in New York promoting a collaboration with luxury pen company Montblanc.

Sales of the limited-edition StarWalker Metal Fineliner pen and matching notebook ($740) will help raise money for the Novak Djokovic Foundation, which supports preschool education in his native Serbia.
