A sleek and elegant pen that writes beautifully, carries comfortably, and catches the eye. The "Ruby" features our bolt action mechanism, inspired by bolt action rifles, which locks open and spring releases closed - and yes, it's a lot of fun to play with. Barrel is crafted from silver ruby lava resin, and trim accents are all in stainless steel. Both the thumb stud and the top of the pen are inlaid with spinel gemstones. Modern mechanics, clean lines, and timeless craftsmanship. Pen measures 5.5" in length.
