DescriptionSpecificationsQuestions & Answers
This wondrously slim eraser lets you precisely erase the areas you want to remove without disturbing the other parts of your work. A mere 4.5 mm thick, the eraser is amazingly compact and barely takes up any space in your pen case. It is made up of a special spindle-shaped powder that not only makes the eraser resistant to bending and warping, but also allows you to erase with the lightest touch!

This high-quality eraser is available in a stylish Royal Blue or Pearl Pink sleeve.

Nearly useless. Not only...

Nearly useless. Not only is it subject to the same skin oil incompatibility problem as most Pentel erasers, where if you use an eraser shield or brush off the eraser with your fingers it will DRASTICALLY reduce erasing power and produce uneraseable black smudges on the paper, but it also fails in areas where it's supposed to be uniquely suited for.

Its form factor, which is supposed to be its selling point, makes it hard to reach sufficient pressure to erase. When used on the broad side, the eraser folds and the erasing area increases, dissipating and spreading applied force. When used on the thin side or on a corner, you do get better pressure, but the thin side is not very different from using a block eraser's edge, and corners can easily break off. Produces a lot of small, fairly messy clumps. Difficult to handle for big hands like mine. Sleeve slides around very easily, too much so I'd say.

At least Pentel's Light Erase and Dust Gathering, which have the same issues with skin oil, have the redeeming qualities of their unique mechanical properties. My advice is to look at the Kokuyo Campus erasers for your lead grade (B/HB or 2B, I use the B/HB variety with 0.3mm B lead). If you insist on wanting to try using this eraser, here are my tips for best results: place the sleeve VERY close to the erasing end (a couple millimeters), erase with the thin side or a corner by being careful, avoid touching the tip of the eraser (if you do just wipe it off on a piece of scrap paper). If you do that then this becomes a somewhat more precise than average eraser with fairly unremarkable erasing power.

In conclusion I'd say that small form factor erasers are a gimmick. If you are familiar with your block eraser's softness and required pressure to erase, you can erase very precisely. Even better if you have an eraser that starts erasing quickly at a lighter pressure, such as my Kokuyo or Pentel's Light Erase. If you have an exceptional need for the utmost precision, you would be better off looking at electric erasers. I haven't had the chance to try any, but their rotating action completely eliminates travel and I think that's the way to achieve ultimate precision, if that's what you need.

Nothing special in terms of erasing pencil lead. It's flexabity and thin dimensions make it difficult to hold and use effectively.

I got a couple of these on a whim just to try them out because I tend to work on a very small scale, and it turned out great! The corners of this eraser are perfect for subtracting out highlights or cleaning up edges on my sketches. I haven't tried taking it out of the little blue sleeve to try the wider ends, but I have a Uni Boxy Eraser for bulk erasing, and the two seem to team up well together.
