Black erasers have become more common in recent years, with the Boxy perhaps being the most well known of the bunch. I have a few that I use regularly, and a few that just lounge in my stationery drawers waiting to be used. As I’m streamlining my sketching kit and the boxy is now the eraser I carry in it, I decided to test it out against the competition, starting with other black erasers.
Here’s the lineup:
In terms of price they’re all around the same price range with the Muji eraser being the cheapest of the bunch, and the dust catch and boxy being on the more expensive side of things.
I took out my Baron Fig Confidant, since I do all my pencil tests on it, and scribbled in it in a variety of pencils and even using a Caran d’Ache red blue pencil, though I don’t expect regular erasers to do well with coloured pencils.
The pencils that I used were the Blackwing 811 (a darker, softer pencil), a Viarco 3500 No. 2 (a standard HB pencil) and a vintage Eagle “Chemi-Sealed” Turquoise H pencil. These seemed like a fairly representative bunch of general writing pencils, at least in terms of graphite behaviour. Though I did later check them for art use, these erasers are meant to be used when writing more than when drawing.
I did a single eraser pass on the left hand side of the page, and on the right side I split each scribble into two and tried to erase it completely (leaving an untouched graphite barrier in between each side).
Then I tried to erase the coloured pencil, which I wasn’t expecting much success in, and here are the results:
A closeup on the one pass side. You’d normally not erase this way, but it does give a good indication of how good the eraser is going to be:
A closeup on the H pencil one pass attempt. I deliberately pressed down on the H pencil, because from my experience H pencils are easy to erase when you apply little or no pressure to them, but they’re pretty tenacious if you apply normal or strong pressure on them.
Here’s the split scribble test above and the H scribble test below:
Finally the Caran d’Ache red/blue eraser test:
At this point I was ready to give the victory to the Boxy, with the Mono Dust Catch a pretty close second, the Staedler Rasoplast in third place and the Muji eraser trailing behind. The Boxy and the Dust Catch also had the easiest “eraser crumbs” to clean (long threads of the stuff, easily brushed aside), and the Muji had the smallest and the worst. None of the erasers damaged the paper, which perhaps isn’t surprising considering that they’re all pretty soft.
I’d also point out that none of these erasers are what I’d call “best”. They’re good erasers, but even the boxy left graphite ghosts behind. There are better erasers on the market, but these in general behaved better than average (even the Muji), and the Boxy and Dust Catch are pretty good. They held up well even against the Caran d’Ache red/blue pencil, which surprised me.
Even though these aren’t “art” erasers, I decide to try to draw some doodles in pencils, ink them with a fine liner and check how much ink each of these erasers lifted.
Here’s the inking. You can see the pencil marks beneath, and I waited for the ink to completely dry before trying to erase the underdrawing.
The results were “ravishing” as to be expected:
You can look at the closeup below and see just how much ink was lifted. These are all terrible for art use, which again, isn’t surprising. I drew an ink line for reference under these, just so you can see how much ink was lifted. Also the top line of left hand dude’s sleeve wasn’t erased so you can compare that too:
The Muji erased faired the best at this part of the test, although I still wouldn’t recommend using it to erase underdrawings.
Of the four erasers that I tested, the Boxy and Dust Catch are the best, and of these two the Boxy is the one I would choose, because of its compact size and its slightly better performance. None of these erasers are terrible, but if you’re investing in a good box eraser (and you should) the Boxy is definitely one to consider.
And why are these black? Presumably to not show dirt, though I find that both frivolous and counterproductive. If the eraser shows dirt, then you know that may need to clean it on a bit of scrap paper before using it, so that it won’t transfer that dirt onto your clean paper. However, I suspect that the real reason is that black erasers just look cool, and the rest is just plain marketing.
