Mad Science Pen Company Beta Type-R Vanness Collaboration Fountain Pen Review

It's not often that we get a pen that is so unique that it's difficult to compare it to anything else already out there. For the most part, fountain pens follow the same basic design language with added flair and character to distinguish the brand. With Mad Science Pen Company, the Beta Type-R is unlike any other pen you've seen or used.

You might remember the name from when Caroline's Meet Your Maker post on Jacob Pawloski, aka Mad Science Pen Company. Jacob's pen turning obsession started around the same time as COVID-19 lock-downs, and it's really impressive and mind-boggling to see how quickly someone can pick up a skill and produce amazing results when they're motivated.

Scrolling through Jacob's Instagram posts features pen after pen that each features a unique shape as well as bright, colorful, even other-worldly materials. The bright and contrasting swirls look like something you'd find in a science fiction lab. It's definitely an aesthetic, and Jacob nails it.

The Beta Type-R is a specific body style that features a friction fit cap, a contoured grip section that partially hoods the nib, and a back section that holds a standard TSWBI cartridge converter. It has all the normal pieces that make up a fountain pen, but they're all unique and fit together so well.

The specific model I have is a collaboration between Mad Science and Vanness Pens. It was a limited edition that sold out in late 2023. And that's something else that makes this pen maker so interesting. Everything is small batch and fleeting. If you see something on Instagram or the website, you better snatch it up quickly before it's gone. Jacob also takes commissions, but you'll likely end up waiting a while (or maybe not — he uses a lottery system to pick the next person in the queue). Before even talking about the pen, I can assure you that if you see something you like, buy it immediately. You won't be disappointed.

The Vanness Beta Type-R that I have features a frosted gray/white section and a swirled purple material that makes up the body and cap. The color combo is definitely more subdued than other materials, but it's just as gorgeous. The resin material is dominantly purple, but there's lots of contrasting colors swirled in as well, like white, dark gray, gray. There's even some areas where the purple has a lovely shimmer or pearlescent effect. It's a lovely material that definitely grabs attention from anyone nearby.

The grip section is made of a semi-translucent light gray material that looks like it should feel like a Dr. Grip grip, but it's actually rigid. I love the way it looks, but I think I love the way it feels even more. It's a fantastic shape, and I love that there aren't any seams or threads to detract from the shape and feel.

The cap on this pen is small! It's about the size of a regular grip section on a standard pen — about 30mm or 1.25 inches. It doesn't post on the back of the pen, but it's easy to hold while writing. What's more fascinating about the cap is the closing mechanism. It uses two o-rings to create a good seal with the pen when not in use. There's also a small hole on the side of the cap to provide air to go in and out when capping/uncapping the pen to prevent any unwanted ink spurts due to pressure changes (at least that's why I assume the hole is there). This little functional design choice is just one example of how thoroughly considered this pen design is.

Back to the grip — it's a first for me in terms of how it shrouds the nib. It's not like a hooded nib — it has a 2-5mm gap between the inside of the grip and the nib, which makes it look like the nib is floating in mid air. If you haven't seen a hooded nib in action, the Parker 51 is a great example. Notice how the nib is meant to look like an integrated part of the grip while hiding the nib and feed. I love how the grip extends halfway down the nib while still providing a substantial grip and flare for your fingers to rest while writing. Since you can hold the pen a little lower than normal, this also provides excellent control of the nib.

Jacob's pens use standard Jowo #6 nibs, and the 1.5mm stub included in mine works flawlessly. Given the excellent level of control I feel I have due to the grip section and light overall weight of the pen, I'm interested in trying a smaller F or EF nib in this pen. I've just been having too much fun using it as-is to perform the swap.

Moving up from the grip, the body of the pen provides a good length for positioning the pen on your hand when writing. It gives you access to the included TWSBI cartridge-converter, which holds quite a lot of ink. Like Jacob recommends, it's best to use a syringe to fill the converter before putting it in the pen. You could certainly fill the pen like a regular converter, but then you have ink all over the section and inside the gap between the nib assembly and inner grip. I wouldn't want the grip to be stained, either! So, follow Jacob's advice and ink the converter before installing it into the pen.

Or, you can always use the pen as an eyedropper. O-rings and silicone grease are included with the pen along with instructions in case you want to go that route. Along with the extra parts, the grip section/body connection has a lot of threads (it takes at least ten full rotations), so I have no concerns that any ink will leak out.

The top and bottom of the pen/cap are almost flat. They are slightly convex and lightly rounded over to give the edges a distinct look but soft feel. One of my other favorite things about this pen design is how all of the mating edges are beveled away from each other. Instead of the surface mating up and reducing any seam lines, the seams are accentuated and integrated into the design. I love the way it looks, though this isn't something that you'll find on all Mad Science designs.

Overall, this pen is definitely a result of something that required a lot of thought and tuning. It's a lovely writing instrument that is a joy to use and look at.

Mad Science pens are typically in the $200 ballpark. I highly recommend you check them out and keep an eye on their Instagram account to be ready for new drops. There's nothing else like them, and they're top-notch writers. Keep up the good work, Jacob!
