I get asked about white pens a lot. I've used one or two in my time and some are definitely better than others. If you're curious about what white pen is best, please check out the review of basically every white pen ever at the Jet Pens blog. There's even a giveaway if you follow the rules at the end of the posting. I love that they give a list of drying times as well as consider the different applications of the pens. My personal favorite is the Uniball Signo Broad (and that goes for their brand of metallic pens too). Now, please excuse me while I go spend too much money on supplies from heaven Jet Pens.
