This eraser is awesome...

This eraser is awesome for those little areas you need to erase. I've been using it for my drawings, and it's great when I need to erase a detail. The eraser itself is a little on the hard side, but it's not tearing up my paper or anything. I don't think it detracts from the quality but I'm sure people want to know everything about stuff before they buy it.

I absolutely love this eraser. it's so clean and quick. And I do love the colors. I love how it can erase small areas so I don't have to break out my eraser guard as much. Definately a must buy.

The eraser works extremely well, and mechanism to hold and extend the eraser operates flawlessly. At 3.8 mm in diameter, the tip is a bit small for general use, so it is not a substitute for a block eraser. Even so, I use this product often and love it.

With this, erasing small areas is easy, but honestly I was disappointed because this is nothing like the usual Tombow Mono plastic erasers. It does seem to be used up very quickly.

I'm satisfied with it...

I'm satisfied with it and it's good for those tiny areas, however I do need to add a more pressure to this than I do with the Sakura Foam eraser which is by far my favorite. This doesn't erase lines with colored lead well at all so when using this make sure you are working with graphite lead. Overall I think it was a good purchase and I like it way more than kneaded erasers, I have three packs of the refills and plan to buy more in the future.
