Works on paper
Since only the most dedicated technophiles believe that the computer will ever entirely replace hand drawing, an attractive effective pen is always welcome. Staedtler has introduced the Mars professional pen, intended for use in both writing and drawing. It uses indelible black drawing ink housed in a 'technologically advanced' ink feed system.The pen has an aluminium finish, with a black grip zone. Line widths are 0.25,0.35,0.5 or 0.7mm, and the recommended retail price is £6.99.
