We’ve always been fascinated by stores that defy the rule of business diversification and focus on only one product. Inspired by the new Rice Krispie Treat store on the Upper West side, we’ve rounded up our favorite one-item purveyors, focusing on the quirkier items you can find in New York City.

1. Yunhong Chopsticks (50 Mott Street, Chinatown)

If you’re only going to sell chopsticks, Chinatown is probably an ideal place for your store to be located. But for the most part, these aren’t the every day chopsticks families use at home, these are beautifully packaged gift items. Our favorite thing though is how the product offerings on their website (called happychopsticks.com) are organized by how many pairs of chopsticks each set comes with, not by aesthetics.
