**Q: How does the writing compare to the pentel rsvp?**
A: I like this pen a lot better than the RSVP. I think they have the tendency to run and it makes your paper(s) messy looking and difficult to read. I threw a lot of RSVP’s in the.garbage for this reason. I don’t like throwing things away if they have a use, but when a pen does this, it’s better to just throw it away

**Q: Is medium the same as 0.7mm or 1.0mm ?**
A: Sure. Keeping in mind that this pen is a total pile of crap. With that being said it goes from 1.0mm all the way to.00001mm in one single letter. It cuts out more than a 13 year old boys voice. Did I mention this pen is a pile of crap? Anyway I hope you make the right decision and use a quill and squid ink instead, old school yet reliable like having a fancy hipster moustache (thats how hipsters spell it nowdays). Hope this helped.

**Q: Do these pens write upside down well? I like to lay in bed and write.**
A: Hello, I had to try to write upside down while in bed, and yes it does write while writing upside down. Who knew, we do now. I wrote for a while and the pen just kept on writing. So that is a pretty neat pen to have. Happy writting!!

My absolute favorite pen! It's inexpensive enough for general use, but durable and writes on stuff at odd angles without "stopping". Highly recommend this pen.
