  The eraser erases very..., March 6, 2010
By jarchie - See all my reviews
The eraser erases very well, but the mechanism that holds the eraser slips occasionally, allowing the eraser to slide back into the holder. I need to extend the eraser often to compensate. The mechanism only slips when I hold the eraser perpendicular to the paper and am pushing down hard. If you only hold the eraser at an angle to the page, friction holds it in place well and you won't have any slippage problems.

If you are considering this product, the Tombow Mono Knock 3.8 is also worth a look.

I really love this eraser. I've had many different kinds of erasers, and this works the best when writing essays(timed) and drawing. It erases mechanical lead better than a wooden pencil. The only problem I had was the eraser ran out fast for me! Good thing they sell the refills!

I work in pencil, so I'm constantly erasing, and this eraser has become my favorite. It erases smoothly and removes pretty much all markings. It's sleek, sturdy, and I like that it does NOT have a rubber grip because I'm allergic to rubber. The price is a great deal, and I'll surely be getting more!

This is a pretty good stick eraser except for one thing; don't ever take the tip off. If you do and then put it back you might start a small hairline body crack that will eventually cause the tip to fall off. I fixed mine with crazy glue and its fine now, except for the cracks! For the price its very hard to fault and I would buy yet another (have two already).

I use this all the time when I am sketching. I have none of the slippage issues and have always found the performance to be perfectly within the range of what I am expecting.

I have used this to erase pencil lines that have been inked over already and almost never have an issue with the eraser streaking the ink (after a bit of drying time). It doesn't pick up too much in the way of residue either, which is very nice as I don't need to "clean" it too much on my jeans.

Highly affordable as well. I've had mine for well over a year and I still haven't needed to use a refill. I might just be stingy, but I can't tell.
