The COPAM does not come with a pen attachment. The pen is an OPTION (!@#$) so remember to order the pen attachment from the COPAM parts and supplies section of the web site at the same time you order the cutter. That way you can set up and test without wasting vinyl.
Also, it only comes with one blade...looks like a 45 degree...might want to order more blades.
By ordering with the cutter you'll save the $9.99 shipping and the extra week to get the stuff.
To quote Roseann Rosannadanna: "Never mind."

You dont' really need the pen attachment. I fit a fat pen into the holder and it works just fine. Anyway, it works just fine and it saved the cost of the pen attachment and the shipping. A stick pen won't work as it is too thin. Has to be a fat pen.

I'd still order extra blades, though.
