This pen is made using a real computer printed circuit board with real components. It is completely encapsulated and protected by a clear acrylic resin. The computer board color is blue. If you are a "computer whiz" or know someone who is, then this is the pen kit for you. Use it daily at the office for a real conversation piece. I turn the clear acrylic resin to shape on a lathe. It is then sanded and polished to a scratch-free glossy shine. •Durable Chrome Plated Finish (also in 24k Gold) •Real Printed Computer Circuit Board •Twist mechanism (push click also available) •Available in other colors, larger sizes, pencil, letter opener, and in matched sets. The Parker compatible ballpoint refill is available at office supply stores. It comes with a black ballpoint. Blue ink, Gel writer and rollerball style refills are also available. See my other handmade computer circuit board pens for other options. Comes in an attractive and durable black velour gift box.
