## Questions & Answers

**Q: is the "7 set" seven packs of four or seven in one package?**
A: Thank you for your question.  I don't sell 7 sets, but 1 set contains 4

**Q: Do these create a lot of tiny bits of eraser dust? Or does the dust roll on itself to create long pieces?**
A: It does not create dust but rolls on itself to create longer pieces.  I love this eraser! It’s also nice because you can make a point out of it.

**Q: Well if people who don't know would stop leaving answers I would not have to leave so many. Now will this fit the paper mate tuff stuff stick eraser ?**
A: Yes. I use them in mine.

**Q: Will this work with Factis BM2?**
A: I'm guessing that's a pencil style eraser and can't tell you if that's going to fit.  Either see factis or buy the tombow mono one, which is a great eraser.

### ⭐⭐⭐⭐⭐ Favorite Knock eraser.
*by N***K on March 20, 2019*

This is hands down, my favorite pencil / knock eraser. I have been using these types of erasers since elementary school, and have tried many out. I prefer this one over the smaller tombows, and over the bigger knock erasers - this diameter is perfect. Another important subject is the fact that this eraser is harder than others. When using a knock eraser, you're almost drawing with it, and sometimes you need to add pressure. With normal brick erasers, this isn't an issue. However, if you're using a knock eraser, if the eraser is too soft it will break off because it's eraser formula is meant for a brick - not a knock eraser. (note my picture of the E-Knock's eraser piece broken off) This tombow has not snapped on me at all with daily use for a long time. I just purchased a second one for my travel bag. It's my #1 and I wish I had all the colors and more.
