Pen Holder and Cartridge Hardware

The pen tool cartridge holds a pen in order to draw designs onto the matboard.

These drawn designs can be quite intricate.

There is no need to worry about bevels being too close together, curves being too tight, or angles being too sharp because the matboard is not being cut. 

The Pen Cartridge is the part that holds the Pen Holder and is inserted into the Head.

The Pen Holder contains the pen you are drawing with, and inserts into the Pen Cartridge which installs into the Head.
