## Questions & Answers

**Q: What does knock type mean?**
A: It's the spring-loaded ballpoint ink delivering system inside the pen cartridge. See the definition here: https://www.google.com/patents/US6193429

**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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth the price.

### ⭐⭐⭐⭐⭐ Perfect pen, especially for small blocks on important documents.

### ⭐⭐⭐⭐ Super fine, but not the longest lasting. do NOT drop!
*by M***K on November 12, 2025*

I need a pen that writes super-fine for small areas. These pilots came recommended by a colleague. They do allow you to write "crazy small", but have two limitations: 1. They don't seem to last as long as other pens with larger diameter balls. 2. If you drop one and it lands point down, rather the pen tip is exposed / out or not, the impact will almost certainly deform the roller head and make the pen useless garbage.
