Passionate about sea turtles? Displaying an eye-catching blue-ocean synthetic Fire Opal on top, our exclusive Sea Turtle Rollerball pen is simply a gorgeous kit! The theme will appeal to anyone with a love for sea turtles or sea life! It starts with a beautiful synthetic fire opal on top, two sea turtles swimming on a stream of water for the clip and finishes with a turtle shell texture pattern on the centerband.  The cap posts on the rear of the pen which features wide threads to prevent cross-threading.
