Yes, the Zebra MX was offered up along with a BX. The price was very reasonable. The build quality is stellar. It’s even superior to the PILOT Grandee Priere. The Priere has plastic parts to its mechanism. And while it has that keen advantage of being retractable, there’s always the concern of moving plastic parts rubbing and thinning or possibly cracking over time (although PILOT uses a very high quality plastic). ← ERROR. Well, this is a surprise. I have a gun metal finish Priere and it has some plastic parts inside. This steel version? No. All metal.
Out of curiosity, I unscrewed the nose cone of the MX and extracted the mechanism. Wow. It’s so overbuilt! And it has a larger eraser inside, that’s definitely much more usable than those mini-peg erasers you usually get in modern mechanical pencils. I will have to do a focus piece on the MX and BX together (plus a direct compare to the Priere in polished steel, which I also have). The BX is very well built too. Rivals the PILOT Laureate.
