Review: Great purchase! - Love, love, love these pens and i was so happy to be able to find them on desertcart because I can't purchase them anywhere that I live! They write so smooth it's fantastic!
Review: Great pens and very reasonably priced for legible writing by me - I've used these for almost 20 years and bought a case of boxes around that time ago after going through school and always being forced to write during recesses and after school at home filling notebooks, but never improving my writings eventually being told to print only, though not type when I tried to save all of us the headache. Regardless I needed to write when building my business and went a bit crazy on buying office products 1st time around and had ordered a case thinking it was a box after I tried several pens ranging from $25 to over $300 at that time, partially to add to the professionalism look for a leader back when technology was very misunderstood and looking maybe 16 still, but coming off as nearly 30 to those that didn't know or ask my age right away and went off demeanor can conversation. Regardless these in medium tip and black worked better then the fancy pen brands and the standard office Bic pens that blue ink was also the primary color used by people then. Seeing how hand writing was a reflection of my businesses as well I made sure to order enough to last a long time, more then I thought I ordered though and feared they didn't make them anymore or the same as I started to get lower on them and finding some fine tipped ones, which don't work well for me. To my own surprises I found some $9 pencil from the 90's a buddy's dad gave me that I was amazed by how well they worked compared to other mechanical pencil's but knew I'd never spend that much or get one, but still use that one and releasee it was also made by pental and they are engineering pencils, which then I had no clue what that really was. Great price especially if you loose things a lot or like have pen/paper within an arms reach of you almost everywhere you are and more so if you don't find the things lost either., some company's would bring me handfuls when I start there since I bring them with rather then raid their supply closets for my office and think they were all fancy and expensive, which they are not, if I could change anything, it would be simply to be able to chew on the caps clip or pen in general wo it breaking.

## Questions & Answers

**Q: Is this pen safe for writing on the back of photos? ("archival"?)**
A: I think it is. RSVP pens are not gel based and don't smear. The writing is very thin. If they are important photos, I would test it out on something else first to make sure you're ok with the results.

**Q: Amazing.  All that detailed information and no indication of whether or not it's retractable.  Is it?**
A: From the description:          "This capped pen is designed for extended periods of use."
It was easy to miss.  :-)  

These are capped, but Pentel does make retractable pens.  

This one is retractable, comes in the same colors and widths, and has refills available.  https://smile.amazon.com/Pentel-Super-Ballpoint-Medium-Violet/dp/B07D4Y7YXY/ref=sr_1_24?crid=IFNOX2JTO73E&keywords=pentel%2Bballpoint&qid=1670173944&sprefix=pentel%2Bballpoint%2Caps%2C117&sr=8-24&th=1

The item on this page is my favorite pen.  I love writing in a fine line.  I have some Pentel retractable pens, but they are medium width.  I didn't know they made fine line retractable pens.    Now, thanks to you, I have found the item I just suggested, so I am going to buy it - in several colors!  

I hope you enjoy these (or the other) pens as much as I do!

**Q: Is this the same bright purple as the energel pen?**
A: Ohh, Lordy no! The Energel ink is much more vibrant. I use this for a correcting pen for my students.

**Q: As the pen gets used, sits around for a while, then does the ink on the tip ever build up and consequentally smear when you start to use the pen?**
A: I always cap mine after each use. I’ve NEVER had an issue with these pens, and I’ve been using them since 2003. They are excellent.
