This is a handy little tool for erasing in tight spaces. The gum is clean and white and leaves no trace of erasure on any of the papers I have used with it.
I LOVE IT! It has made it so easy to put in highlights and to erase small areas easily and accurately in my pencil drawings. My frustrations at smearing, inaccurate erasing, and too wide highlights in small places are gone.
The refills fit this one. I ruined the last one because the refill wouldn't fit. I shaved the refill and jammed it in. And then it wouldn't move.
I became aware of these watching someone else use them in a drawing, and said what is that and where do I get one, of course its Tombow! So excited to have this I. Unset
I love the concept of this eraser, but I've had limited success using it. It's not that the eraser is too small, because it's clearly intended only for precise areas. It's that the eraser isn't especially effective on any but the lightest of pencil strokes. I've found it considerably more practical to use the Mono Dust Catch eraser, even for tiny spots. The size and weight are perfect, though. If the eraser could be replaced with the Dust Catch kind, this would be a 5/5 for sure.
