Rapidograph Stainless Steel PEN 3165 1/0.50
Kohinoor's technical pens are for general technical drawing use when you require a constant line width. The plastic body encases a stainless steel tip which screws into the main body of the pen and is removable for cleaning or replacement. A plastic ink cartridge is popped into the pen body. Pens should be cleaned on a regular basis so they won't clog. 3165 Series.
