Penbbs 350 Review - Fountain Pen & Rollerball Combo

Recommended Posts



For a moment there, orange was my color of choice. I think I was coming off a sepia phase, but don't rightly recall. I got myself some Diamine Autumn Oak and took a flyer on J. Herbin Orange Indian.



J. Herbin Orange Indien

The Autumn Oak was a great success but I could never get the J. Herbin to work for me. None of the pens I tried would make a go of it. It was my first out-and-out ink failure.


So when I unboxed the PenBBS 350, I did two things. First, I swapped out the fountain pen nib for the rollerball. Then I filled the pen with Orange Indien.


I was being a little perverse. Like many, I write with a fountain pen unless I can't help it. You know the type. (You may be one yourself.) But I was impressed by the moxie PenBBS was showing by including a rollerball with the pen. They were thinking outside the box.


To reward the daring, I gave the pen the hardest ink I have. To my surprise, it worked.



Truth be told, I think the J. Herbin ink has darkened over time.
Looking at some old notebooks, it looks a bit brighter.



Conceptually, the PenBBS 350 combo hits it out of the park. I love the idea of including a rollerball in the mix. It fits the style of the pen and it writes very well. The line is satisfyingly bold and the rollerball is smooth, agile and consistent.


Ergonomically, however, the rollerball isn't a complete success. The rollerball tip is much shorter than the the fountain pen nib - making the pen just that little bit smaller in the hand. The balance between the girth, length and writing experience is slightly awkward. After writing with the rollerball for a bit, I swapped in the fountain pen nib and felt much better.


In its fountain pen configuration, the PenBBS 350 rocks:

  • The size is perfect. The diameter is fat enough to be substantial and the unposted length is just right for my hand. The pen posts well enough but that's not how I use it.
  • The weight is spot on. Weighty enough to feel intentional while remaining nimble. Long writing sessions are no problem with this pen.
  • The texture of the pen is light but real: a matte finish with just little grip. Nice.
  • The threads are fine and not bothersome. They work as a midpoint reference for keeping the pen oriented in the hand by touch.
  • The cap comes off in under 1 1/4 turns making this a fast pen to cap and uncap.
  • The cap facets keep the pen from rolling about when not in use and, of course, mean the cap is less likely to wind up on the floor when using the pen.
  • The cap uses plastic interior threads so you don't have the potentially annoying metal-on-metal feeling when capping/uncapping the pen. The action is nicely smooth and precise.
  • There's no clip but that's not a bother for me. I don't need one.
  • The nib is the same PenBBS F No. 6 that comes with their other pens. It's a great nib and performed up to expectations out of the box.





Given the aluminum construction and minimalist, industrial design, I put the PenBBS 350 in the workhorse camp. It's durable and functional and could easily serve as a beater pen for everyday use. It works as a full-sized pocket pen.

  • Length capped: 130mm
  • Uncapped Rollerball: 117mm
  • Uncapped Fountain Pen: 122mm
  • Weight capped (inked): 23.1g
  • Weight uncapped (inked): 15.7g



I like the style of the pen. It feels modern. I'm becoming a bigger fan of the PenBBS brand. It could easily be the best Chinese pen brand today.

At under US$15 on Taobao, it's a heck of a value.

  • Would I recommend this as a first fountain pen? Yes. If someone is going to catch the bug, this is as good a vector as any.
  • Could this be someone's only fountain pen? Well, it could. If there are folks out there who can eat just one.
  • Would this make a cool gift for a fountain pen friend? I think so. It fits the ideal of something different that lots of people might not pick for themselves.

Thanks for the review!

I was also impressed about the idea of fitting a rollerball pen and a fountain pen in the same body.

And I like the peculiar mint-turquoise color of this model.

There's a bit of a frenzy on their official Etsy and eBay.com shops for the red and blue ones which were launched today. And a second black colour that's somehow different from the first. (Shadow vs Obsidian)

I can see why, the blue and red is appealing and I feel it is "that" shade of red and blue that most people love.

The shadow with two tone nib are gorgeous also, but you know what would seal the deal for me? Obsidian / shadow with a black nib, go full stealth

Did a review on the "new" red 350 with two tone nib, to watch skip to 7:55. Have a green & black "older" model. Differences I found were minor. It is a great pen, I enjoy writing with it. But then I like metal pens.

      Not sure if this has been suggested already but would a setting for localized regions or chapters in FPN be helpful? I don't know if there is a way to find local FPN members who would be nearby. I don't know if we want to be discoverable but a setting to know how many members are in 25, 50, or a 100 miles of each other might be helpful. We can create a regions specific network like Craigslist where people could use that to connect with nearby members, conduct in person sales, arrange FPN meetups

      Hi again all, I forgot to tell y'all that I made the post about Sweden ink PIF. Most have probably found it long ago, but here's a link, anyway:

      I read your blog post and all the replies with much interest. I'm a FP user in Australia. Been part of this forum for years but rarely post. I did come across your ink sharing thread and considered participation. For me it's not lack of interest but lack of time to play around with FP and inks. I'd feel bad to put my hand up for the box and just have it sit until gosh knows when...   I also think that the FP community in Australia is smaller, and I wonder how many in the community are

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav
