This is a very special pen for that friend or employee that loves to work on computers. It is an actual circuit board that is encased in acrylic. As you can see bhy the two different pictures, the pen also comes in an orange circuit board in the acrylic case. I have turned the pen on my lathe and placed it in the Sierra pen kit. I do have these in stock, so they are ready to ship right away when orderd. Since the pen is really a circuit, it is a little more expensive than the regular Sierra pens. This pen would be a special gift to that IT person who loves the unusual. It will draw the attention for whoever receives it.
