"I'm finding that there's no one demographic - it's across the board," Rovner said. "There's the young guy who wants to use a magic trick to meet a girl at a bar, there's the grandfather who wants to impress his grandkids."
Rovner, who has spent most of his decade-long career working in New York City and Los Angeles, opened the shop two years ago after he saw a void in Philadelphia's magic scene.
Hocus Pocus Magic Shop, just off South Street, was for years the city's shop for both casual and professional magicians. It closed after the owner's death in 2007, leaving Philadelphia's magician community with nowhere to go.
"I just saw an opening to bring magic back to Philly," Rovner said. "There are a lot of magicians who live and work here, and I think there was a need for a store like this."
According to Mark Weidhaas, past president for the Society of American Magicians, Rovner's timing may have been spot-on. Philly is home to the second-largest local chapter of the organization, with about 120 members, Weidhaas said.
"We see Philadelphia as an up-and-coming place for magic," he said. "New York has always had a couple of shops, but for people from other areas, Philadelphia may be closer. So it would be a great location for a shop."
Trick Zone sells gags for practical jokes, but also tricks that require practice and patience. Rovner hosts magic shows on Thursday nights, often bringing in other magicians to perform for an audience of a few dozen. He said his business is steady, and he often draws customers from out of the city and state.
