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.
