I emailed Pilot Pen to see if they make a water resistant rollerball pen. They don't, but they did send me samples! I'm not sure what the difference is between the V5 I buy at Staples and the P-500 pens they sent me; they pretty much write the same. Too bad Pilot doesn't make a pen that's water resistant. Then I could be truly fulfilled as a doodle artist. Ah, well.
