This is by far my favorite eraser. Not just because it holds well and doesn't cramp my hand like the small block ones. Not even because it lasts a good while. It is because it is actually a very good eraser! I use it to clean up sketches with blue pencil and it's like watching a Mr. Clean Magic Eraser on grease stains.

I love it!

Eraser works well for HB and B leads, even with hard-pressed writing.

This eraser erases easily with not much pressure. I like the retractable style because it keeps everything clean and also stops the little eraser bits from getting all over my other pens. Overall, a really nice eraser, especially for students.

Amazing.
The problem I always had with erasers is that when it becomes small, it is hard and sometimes painful to use it (when I burn the tip of my finger on the paper). This eraser solves that. It is also black so after erasing with it , it won't look dirty . Also unlike other retractable erasers it wont retract when you are erasing and push too hard. Absolutely a purchase I don't regret. Recomend to everyone.

Best eraser I've ever bought. It doesn't leave anything behind. No streaks or smears. Will buy again and again.
