HARTFORD, CT–Four days after the arrival of a shipment of office supplies from Staples, P&K Insurance office manager Patty Hildebrandt, 41, remains ambivalent about Sharpie's new "Twin-Tip" double-ended permanent marker. "Putting a fine tip and a broad tip on the same pen is very convenient, not to mention cost-effective," Hildebrandt said Tuesday. "Still, neither of the twin tips really works as well as a single-ended marker, probably because they're sharing the same ink." Hildebrandt recently took a strong stand against 3M's accordion-style Post-It notes, calling them "an abomination."
