The eraser erases very...
March 6, 2010

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!

This pen-type eraser has replaced the traditional block eraser in my pen case. It fits well among the pens and is fun to use for erasing a letter or two. I wouldn't use this to erase a wide area, this eraser is meant for correcting small mistakes.

Works well, but leaves a fair amount of residue.
