This is a beautiful pen. When I'm not using a
pencil I prefer a fountain pen, and if for some
reason I can't use a fountain pen, I favor a Pilot
G-2 because it writes well and I can afford to
lose it. But I was intrigued by the Einstein
Retro 51 because of the theme, and I already have
two Retro 51 pencils and love them. So I decided
to try the Einstein roller ball. It's gorgeous.
Of course the equations are there sharp and clear,
but the metal parts have an understated burnished
look which I much prefer to the fake golden look
on some of the other versions. And most
important, they pen lays down a clear black line.
None of that skippy-skippy stuff. It's smooth and
a pleasure to write with.I don't know how the finish will hold up....
