I was recently browsing the pen aisle at a local office supplies store and noticed something new - the Faber-Castell Eraser Pen, article 183998 in its blister pack form.
As noted above, the visual styling is classic Faber-Castell and I find it quite appealing. The grip is hard plastic and despite the grooved rings is somewhat slippery, but you usually only hold a stick eraser for a few seconds at a time so that’s not a major concern.
The Faber-Castell Eraser Pen has two uncommon features. First, you extend and retract the eraser core by twisting the tip. No push top button or slider mechanism like many other stick erasers. This does have an advantage in that unlike some stick erasers the core doesn’t push back inside the body under heavy hand pressure. The second unusual feature is that the eraser core is only short, about 29mm (1 and 1/8th inches) long, and three spare eraser cores are stored inside the body. You unscrew the body to get to the replacement cores, and then feed them in through the front of the tip.
Right then, let’s put the Faber-Castell Eraser Pen up against my test bench standard, the Staedtler Mars Plastic. The first thing I noticed is that the Faber-Castell eraser is hard and abrasive. It feels it, and it sounds it - completely different to Mars Plastic, and not in a good way. The eraser waste is somewhat crumbly compared to Mars Plastic – it doesn’t twist up easily into long strands.
Expectation and outcome?
