I've been writing my lists and notes with an amethyst Le Pen by Marvy Uchida that I bought the other day. I'm thoroughly enjoying it. Le Pen is such a funny name, very 70's a la Haagen Daz. Probaly an advertising stroke of genius in its time. Now a days it's hard to even find them in a store. But if you spot one, snap it up and really enjoy some good old fashioned handwritng.
Here's another online source. I want to buy the 18 pk.
