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!

I've had mine for over a year and I use it almost daily. It's my go-to eraser -- I love that it's simple yet sturdy and reliable. Erases clean and neat. It's a good little worker bee!

This is a nice eraser which is thinner than others I have used. THis is another item I keep as a staple in my teacher pencil case.
