## Questions & Answers

**Q: Does this pen have refill cartridges, and if so, which?**
A: It does have refill cartridgeshttp://www.amazon.com/Uni-SXR-7-Jetstream-Ballpoint-Refill/dp/B002H9W9P6/ref=pd_sbs_op_9

**Q: Can you write in any position with this pen? And has anyone used it for outdoor work under different weather conditions? Like to know your experience.**
A: You cannot write with this pen inverted. For example, if you are going to write on the wall, it will not work for more than a few seconds.

**Q: When pressing the top of pen , does it make any noise ? I love that clicking noise while waiting in between writing .**
A: Yes, it has a nice click! I love everything about these pens. One of the smoothest I've ever used, and the red is more vibrant than you would think.

**Q: Is it a good pen for left handed people? Most pens don't work well for me as I write from left to right.**
A: I'm left-handed and have explored more than a few dozen pens, this one is my favorite. It writes smooth and is quick dry to prevent smearing, not as quick drying as some but I really enjoy writing with this pen and have had no issues with smears or ink on my hand.
