The bug hit HARD today. I have a Smith & Wesson tactical pen that was a Christmas gift, really cool blue color. I remembered that Lamy likes their colors, and found an Ocean Blue that would match my other pen almost perfectly (Rollerball/Fountain pen color coded combo!!!) Found that World Lux in Seattle had them on sale. Contacted them, and SOLD OUT!!!!! Remembered seeing them at the University Bookstore while hunting for gift for wife at xmas. Called, they had one in a medium nib, but it was $10 more than sale price. Long story short, wound up buying it and a converter, plus a pack of cartridges. Now for the question of the day. Which BLUE ink should I purchase?????
