Introduction

Some pens earn their place in a rotation because of how they came to be, and the William Shakur Titan 720 is one of them. It started as a conversation: the owner of an Omas 360 loved that pen’s rounded triangular profile but hesitated to use it often, because the Omas piston and cap are known to be somewhat fragile. The request was simple: could a 3D-printed pen capture that same triangular character in a sturdier form?

Who This Pen Is For

The Titan 720 is for fountain pen enthusiasts who enjoy oversized, unusual pens and who appreciate the story behind a handcrafted piece. William Shakur is not a retailer with a web store. He is a private maker who occasionally produces pens and sells them to interested buyers. The only public contact point is his Instagram profile, william.shakur. There is no website, email, or phone number, so if the triangular shape intrigues you, reaching out through Instagram is the only route.

It also suits anyone who has wanted the Omas 360 experience without the worry. Because the barrel is so large, it holds what can only be described as a titanic amount of ink, and one fill can keep writing for about a month.

Design and Build

The Titan 720 is 3D printed, and the finish is polished to remarkable smoothness. From a distance it reads as a black pen, but up close there is a very dark, almost eggplant-like purple tinge that gives it real character. The triangular profile is clearly present, with visible edges, yet the grip section is more rounded than the original Omas 360, which makes for a genuinely pleasant hold.

The name is a playful nod to its inspiration: 720 is two times 360, and the pen is bigger than the Omas in every direction. It is genuinely enormous. Compared with a Pilot Metropolitan or an Ensso Pocket Pen, the difference is dramatic, and it turns heads every time it comes out of a pocket.

Key Features

The Titan 720 uses a working piston filler that is sturdier than the Omas piston it was inspired by, along with a functioning ink window. The nib is a titanium number 8 paired with an ebonite feed, and the maker’s circular logo adds a neat finishing touch. The number 8 nib looks almost modest on this body, which tells you everything about the pen’s scale. With a number 6 nib, it would look badly out of proportion.

How It Writes

In use, the titanium nib has a bit of a sweet spot and works best with very little pressure. It can be slightly finicky, and while it is tempting to chase strong line variation from a titanium nib, those nibs can bend out of shape if pushed too hard, so a light hand is the right approach. The generous ink capacity means the pen stays inked for weeks at a time.

Things to Consider Before Buying

The triangular form will not suit every grip, even with the softened edges. Availability is uncertain: the maker has indicated that the triangular work is very labor intensive and may not continue, so sourcing one means contacting him directly and seeing what is possible. And if you prefer discreet pens, a near-oversized triangular conversation starter is the opposite of subtle.

Buying Advice

If you love the Omas 360 silhouette but want something you can use daily without anxiety, the Titan 720 is a compelling answer. The combination of a durable piston, a rounded triangular section, and an enormous ink capacity makes it a genuine user rather than a shelf piece. Reach out via the maker’s Instagram to ask about availability.

Conclusion

The William Shakur Titan 720 is a rare kind of pen: a 3D-printed, hand-finished piston filler that solves a real problem, in this case fragile triangular elegance, while being genuinely fun to use. It is big, comfortable, and endlessly interesting, and it earns its spot in any personal pen series.
