Uni-ball E-Knock Eraser - White Body

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 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.

Love this eraser! All the convenience and maneuverability of the ubiquitous "Clik-Erase" but with an excellent eraser - soft touch, clean erasure, so perfect!

Love this eraser, used it a lot when I was classically animating

This is an AWESOME eraser, but the spring of mine keeps popping out so I use the Mono Knock 3.8 now.
