Description This hardware produces a refined pen that is similar to the original Gatsby twist pen, with two ribbed bands, a domed end and black accents, but with a thicker, more substantial design. Available in three finishes: gold, gold and gunmetal, and chrome and gunmetal. The pen operates with a half-twist, comes with black ink and takes Parker-style refills. Requires a standard "A" mandrel, a bushing set, a 3/8" drill bit and a minimum 3/4" × 2 1/2" pen blank, all sold separately. Because mishaps can occur during turning or assembly, we also offer brass replacement tubes.
