It's comfortable, easy to hold and a pleasure to write with. Plus, our 24kt gold uses a "premium rack plating" process and is covered with an exoxy coating for extreme durability. We guarantee its beauty and durability with a lifetime guarantee. Requires a blank 3/4" x 3/4" x 3". Features a premium click mechanism with parker style refill and is pre-assembled for very easy turning and assembly.
