REVISION (from review on black body) --- This pens barrel, based on my use at my
desk, is prone to cracking, and making the pen unusable. This may be because of
the increased barrel weight if it is dropped. This pen has become non
functioning after limited desk use, due to barrel cracking by a drop of 3' (desk
height onto vinyl flooring).
Good while it lasted, but it did not last long. My Zebra was well over a year
and still going.
