The Pilot G line was so popular that Pilot created multiple versions of it. You can practically trace history at JetPens as you scroll through the G-1, G-2, and G-3 lines that we have here. The G-1 Grip pen is a relatively older model compared to the modern G-2 and G-3 pens. But it still has the same smooth flowing ability and quality writing power that the G line is admired for. This particular model was highly requested by our pen spinning customers, as the grip can be used to create many pen spinning mods. Black, blue black, green, blue, and red ink pens are available.
