I’m a fan of Big Idea Design (BIGiDESIGN) and have been for years. I’ve supported many of their kickstarters, and they make some of my favourite pens and I have reviewed quite a few of them: Ti Arto Review, Ti Arto EDC Review, BigIDesign Dual Side Click Pen Review, BigIDesign Pens Overview.
When they originally came out with the Fountain EDC, their first fountain pen offering, I decided to not purchase it. I don’t generally like metal fountain pens, and I rarely use pocket fountain pens because of the hassle of posting them every time you write.

So how did I end up with a Fountain EDC?
I backed their kickstarter of course. Big Idea Design launch all of their products via kickstarter, and this one was no different: a kickstarter for an Ultem Fountain EDC made in the USA in their new machine shop there.

The ultem rage swept through the fountain pen community in recent years (? it could be months, time is meaningless to me since cancer and COVID), and left me cold. I found the material ugly, and the fact that it was touted as extra light and durable didn’t make it more attractive to me. It’s basically a plastic that’s available in black or a singularly ugly orangey-yellow, with certain chemical properties that aren’t very applicable to fountain pens (are you steaming your fountain pens or boiling them regularly? If so, ultem might be for you but fountain pens are clearly not). I’m being cynical, I know, but there’s a twist, I promise. It all works out in the end.

Big Idea Design generally work with titanium, so seeing them use another material was intriguing. It was also a material that is perfect for an EDC type of pen, as it’s both light and durable. The yellowish colour also works well with the matte grey of the titanium hardware that they selected for this pen, and unlike other ultem pens, the price of this one was reasonable. So I decided to try the ugly plastic and see what all the fuss was about.

So I backed the kickstarter and the pen arrived very quickly (Big Idea Design kickstarters work like that. They deliver on time, and fast). The box was the usual great Big Idea Design box that they’ve been using in recent years, and it came with a sticker and a tiny velcro rubber patch – very cool.
I was stunned by weight of the pen.
It’s a pocket pen, so it’s bound to be light, and I knew that ultem is supposed to be light, but it’s jarring how light it is. The ultem had a nice, matte finish, the ugly yellow did work well with the brushed titanium clip, but the entire weight of the pen is basically in that clip and the (Kaweco) nib.

This pen has to be used posted, it’s just too short to use it unposted, much like the Kaweco Sport. There’s a step in the back and an o-ring on the cap that make posting supposedly more secure, but you need to make sure you’re applying enough pressure when posting or the cap will go flying off. On the plus side, the cap is made of ultem so it will likely be unscathed, but it really isn’t the most convenient experience.

In terms of size it’s about the size of a Kaweco Sport, just a smidge longer, when capped:

However, things are different when the pens are posted: the Fountain EDC is significantly longer than the Kaweco Sport. It would be much more comfortable for long writing sessions than the Kaweco Sport if not for two flaws in the design: the cap posting, and the ink flow.

I mentioned the cap becoming easily unposted before, but it’s worth mentioning again. The design of the pen is such that you really need to push the cap on to pen body and check that the o-ring is engaged, otherwise the slightest jarring will pop the cap off.
The second flaw is the most major one with this pen, and it’s a big enough deal that it makes me not recommend this pen until Big Idea Design solve it. The pen has a very, very hard time starting. It’s not related to the cartridges you choose to use, but rather to the design of the nipple that connects to the cartridge. Enough Kickstarter backers had this issue for Big Idea Design to post a YouTube video addressing it. They say that it’s the coating they put on that nipple, and that taking a pin and scraping that coating off should help. Well, I did the procedure more than once with various tools and it helped a bit, but the pen still requires literal shaking every paragraph or so to get the ink flowing again after it dries out.

As this is the only fountain pen I used as I was travelling for three weeks, this was very frustrating. I love the feel of the pen, but the ink flow issue, the cap issue, and the weird balance with the ultra-light ultem material that makes this pen very back-weighted when posted makes this not a product that I would recommend.
The back-weighting and the cap posting issue should have been taken into account during the design process. The flow issue should have definitely been caught during production, especially as it’s a made in the USA pen (i.e. local to the Big Idea Design people, in a shop owned and operated by them).
So bottom line:
I really wanted to recommend the Fountain EDC but I really don’t. The pen needs to be redesigned to have better flow, better balance and better capping.
Ultem itself is as ugly as I thought it would be, but it’s a lightweight and durable material with a nice feel to it, so I get the hype a bit better now.
Product design is difficult, even for experienced designers.
