## 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.

Oh my gosh, these pens are perfect. The ink doesn't run out too fast, the point is perfectly thin, ink doesn't smear, even when it gets wet. They are extremely comfortable to use, and don't slip out of my hand. I'm absolutely in love.
