Oh no!!! I only use 2B lead, and I thought, yeah, right, an eraser that works better for one lead or another. But... it does. It erases cleanly with less pressure and leaves fewer eraser crumbs. My friends who make fun of my office supply addiction will never let me live down that now I have specialized erasers to go with my over-the-top awesome pencils. :-)

I was surprised but it actually erases better than my standard Staedtler Mars plastic. It is less abrasive and has less crumbs. It is now my favorite eraser when sketching with my 2B mechanical pencil.

This eraser is noticeably better. Leaves a fair bit of residue, but removes markings better than others and requires less effort (lower risk of tearing or crumpling paper).

Awesome eraser that does the best job on soft lead!

What is not to like? awesome job on all fronts. i use it on 2b and 4b lead and it does a perfect job with minimal shavings. Doesn't get any better

I went on en eraser bender and bought four types. W Foam; NP Mono; Staedtler Mars Plastic and Campus 2B.

I tested them using 4B lead on writing and darkly colored-in areas. The results were clear in various tests, the conducting represented a nadir of procrastination. Campus 2B was the only eraser that completely erased everything. The W Foam came in second, but not close, as the texture of the 2B is soft and doesn't require a lot of elbow grease. Also, the 2B does not turn black, like the Staedtler does. This is an absolutely amazing eraser. It's in a class by itself.

The NP Mono is not only the smallest eraser - most expensive - of the lot - it performs poorly, always leaving a trace of the lead behind.

For decades I have trusted Staedtler Mars Plastic. I'm sorry to say that that's now been supplanted forever by the Campus 2B. The SMP is nothin next to the Campus 2B.

This Campus 2B eraser is the best I have ever used.

The Campus 2B beats out my usual favorite, the Ain Dust-Gathering, when it comes to erasing soft lead--it definitely won out when erasing 4B Tombow Monos on smooth Bristol. It is also very good at gathering its shavings up into a convenient single thread as you erase.

I bought nearly every block eraser that Japan makes in a recent shopping binge. As a math major, I need lots of erasers as it is, but I also wanted to determine which ones worked best for my needs. I tested all of the erasers on three different types of pencils: a Pilot Eno color .7, a Pentel graphite .5 and a Pentel color 2mm, and then on three different paper types: Rhodia, an index card, and then plain old American junk copier paper.

The type of paper wound up not mattering with the performance of any of the erasers. What mattered was what lead they were erasing.

So with that established:

The Kokuyo isn't a very sexy eraser. Other erasers have a certain wow factor, like the Boxy and it's sleek black square that's so easy to hold, or the Seed erasers that glow in the dark, or are made of cute colors, or come with a sophisticated gold eraser holder.

However, the Kokuyo is a workhorse at what it does: Erasing. It was easily a top 5 eraser when it came to .5 and .7 leads, and it required very little effort to clear heavy marks.

It doesn't work so great on the 2 mm Pentel color leads, which are supposedly 2B in lead hardness. The Kokuyo requires a whole lot of elbow grease to get Pentel Color marks to clear out, and, even then, it leaves some of the color behind. I use the Pentel every single day for graphing, so I need an eraser that can handle that. It's sort of the deal-breaker, and the Kokuyo failed there.

I'll keep it around for normal pencil tasks, because it does so well at those; however, I won't be buying more.

As a student with a campus, Kokuyo Campus Student Eraser has been my go-to eraser for sketching, computations, scantrons, crafting and all other erasing needs. I have yet to find an eraser better suited to my needs that erases almost always without a trace.
