On a recent trip to Texas I came across a library book store selling Leuchtturm1917 Drehgriffel gel pen refills. At the time I was looking for something, anything to replace the Schmidt P8126 cartridge I was stuck with. Well, after a slightly rocky start, the Leuchtturm1917 refill was writing surprisingly well for a gel refill in the Parker-style format. I decided upon my return to California that I would seek out the full pen experience to get a better picture of the product.
