I've tried Hobby Lobby (where I originally bought the set of four pens quite a few years ago), JoAnn Fabric, Michaels, Staples, Target, even Walmart, and not one of the stores carries these pens in-house. Is there some sort of exclusivity agreement that I am unaware of, or is this Pilot's plan to increase demand by making them available, same day anyhow, to no one? For every 25 things I walk right past in Hobby Lobby that I can't imagine being more popular than a Parallel, I may walk past 1 thing that is. Heck, they even started carrying those Speedball brand oblique holders, which I get may be appealing to someone just starting pointed-pen, but for the rest of us, they're more limiting than anything.
I forget, is there a cartridge that is compatible with the Parallel? I dont do much broad edge calligraphy, so pardon me for being a moron.
