The Platinum Preppy fountain pen is one of the best values for the money! This is a fantastic starter fountain pen, or great for lending to a friend. This pen features a translucent green plastic body, a clear cap, green trim, and a stainless steel nib. As a Japanese-made pen, the nib runs on the narrow side. The Preppy accepts proprietary Platinum ink cartridges (one green cartridge is included) or a Platinum converter (sold separately) to fill with bottled ink.
By converting this pen to an eyedropper, you can fill the entire barrel with ink for maximum ink capacity! All you need to do is add an o-ring and a small amount of silicone grease to the threads (available separately).
