Sketch Pen and Pencil

This is the pencil you want if you do a lot of drawing or diagraming or you have a workshop. The lead is large enough not to break it and long enough to last a long time and if you wife comes out to your shop and ask you to sign a check. No problem in looking for a pen. You just push the pen plunger down and drop out the lead and insert the pen cartridge and keep moving. This would impress your wife as someone being able to work under pressure.
