The Silhouette pen holder adapter lets you use almost any pen to draw with your Silhouette machine. I has 3 different-sized collars that will fit many different pens. There's no need to use a Silhouette sketch pen in the holder, you can use a Sharpie, a ballpoint pen, a pencil, and many other types of marking pens. Just select the collar that best fits the pen, and use the pen holder in place of the blade with sketch pen in your cut settings.
