Well CATTY1 the plotter has a pen holder similer to the cartrige holders and the pens are alittle smaller then a reguler pen, but the whole thing is out in the open. It stands about 4 ft tall and about 5 ft long. So yea then can get a pretty good run on the cover I made. With a good run and no brakes at that altitude they land about 6-8 ft from the plotter. At lest they don't go to work on the roll of paper or the paper coming out.
