The response to the X-Pen over the past several days has been incredible! We've had several people mention that they want a cap for the pen, though. So, we looked at a way to put a nice cap on the pen, and feel that we have a great design. It's simply a carbon tube with a stainless tip. It looks great! Here are a few pics: We're going to offer it for $50 (no base is included!). Let me know what you think!
