## Questions & Answers

**Q: What does knock type mean?**

**Q: Is this product refillable?**
A: Yes they are refillable. Look for BRFV-10EF-B for 0.5 mm refills.

**Q: Is this a gel ink or just regular pen?**
A: I nither gel or regular ink, this pen use a hybrid oil based ink, they write very smooth, don't smear, and always write until you deplet the entire ink inside the barrel. You won't be disappointed. I am a nurse, and I don't like to use crapy pens.

### ⭐⭐⭐⭐⭐ Review
*by D***H on 21 November 2023*

I had bought these pens a few years ago at Walmart but they didn't seem to carry them any more and was thrilled when I saw them on Amazon. I ordered a packet which I had finished not long ago and so ordered another packet. They write so well and hardly ever smudge. They are a nice thin point and don't leak but they just make such a good job. Once you have tried them you will not want any other pen.
