The inner lead reservoir is plastic, but terminates in a metal collet on the eraser end (plastic eraser collets tend to expand over time). The eraser cap is made from metal, and it has a small amount of play with the body that causes it to rattle I fixed that with a small piece of packing tape, similar to the 800 tape fix. It should be quite hard-wearing, but I havenРІР‚в„ўt had it long enough to speak of long-term wear. The iron-plastic material is weakly magnetic, denser, and gets noticeably cold to the touch. The barrel is made from two materials, iron-particle packed nylon and either raw nylon or ABS (IРІР‚в„ўm not sure which). Pentel definitely falls into the latter camp. There are two possible reasons one would use plastic because itРІР‚в„ўs cheaper, or because they feel itРІР‚в„ўs better suited to the purpose. Pretty damn good.Р”В«ut thatРІР‚в„ўs enough about 0.2mm lead, letРІР‚в„ўs look at the pencil. ItРІР‚в„ўs gotten to the point where I feel like 0.5mm is just too blunt a tool for my math, so IРІР‚в„ўve decided to try 0.2mm. But at some point, I think at the beginning of my PDE class, there was a fundamental shift.

At the time, and indeed for years, it served my purposes perfectly. I got my 800 at the very onset of my love of math, some time just before Algebra 1. However, there is one issue I cannot fix: The lead is too thick. IРІР‚в„ўve taken it to bits to fix every little issue IРІР‚в„ўve ever had with it, including the tip-wobble. ItРІР‚в„ўs a great pencil exceedingly well built, reliable, and good-looking. IРІР‚в„ўve had a Rotring 800 for the past several years, and IРІР‚в„ўve used it nearly every day in that time.
