Query: Pilot G2 Retractable Gel Ink Roller Ball Pen

When I learned that personal checks should be written ONLY with black gel ink to prevent forgers from bleaching out and rewriting those checks, that's when I became familiar with Pilot gel pens. Not only do I fancy them, I have to keep a close eye on these pens when friends "borrow" them. Yes, they are THAT good! I soon realized that I was depriving myself by not owning the red pens also. So far, the red pens are performing as well as the black ones do. There's a reason that Pilot G2 pens are very popular - they are comfortable and perform dependably.
