Basically a Rotring 600...

Basically a Rotring 600 for a few dollars less. While it feels slightly lighter
then my Rotring 600 it is of the same quality. In fact I use it more often then
my Rotring as there is almost no build up of dirt in the cross hatching. Plus
the white looks so cool. As far as differences the Retro 51 is almost exactly
the same. The main differences is that the Retro 52 has a retractable tip but
does not have a lead type selector which the Rotring has. Both the Rotirng and
the Retro 51 are great pencils and I love to use them both.
