Your ancient pen is out of ink. You try to refill it. But nothing works. It seems as if there's nobody you can talk to. Roxanne Hill understands. "The older generation, the kind with walkers, that's all they come in for," Hill says. "They depend on us for that sort of thing." Hill's family has been putting precision writing instruments back in working order since they bought this stationery store on Geary Boulevard back in 1969. When Hill took over the store from her father in 1990, she allowed her personal taste for designer towels and children's books propel a drift away from the core mission. But the drawers of pen refills stayed. "We kept the pen refills going, because people came in for that," Hill said. "People bring in their old fountain pens, Parkers, Cross pens." If your old pen is discontinued, and no refill exists, no problem. Hill's husband, Scott Brodie, has been known to conduct extensive research to match off-label refills to antique pens.
