Introducing the Quark, a pocket fountain pen that redefines compact convenience without compromising on performance.

Featuring the new ACME double-start cap threads that offers a smoother capping and posting action, increase wear resistance and improved seal, the Quark effortlessly unveils its nib with just 0.6 turns. When posted, the cap securely threads onto the back in a mere 2 turns. The 22mm-long section, ranging from 9.85mm to 9.0mm in width, is precision-engineered from grade 5 material with micro-machined grooves and a bead-blasted finish.

Delightful little pocket pen

I bought this as I have the Namisu Pocket Nova in ultem and wanted something thinner but with a #6nib. This pen fit perfectly, now may need to get more nibs for it, and possibly a second one.

The greatest pocket pen ever!

This is my favorite pocket pen there is. Super small when capped but extends to a great length for even long writing sessions. Feather light in your hand and glassy smooth with delicate, yet stirdy threads. The nib is also excellent, smooth writing that isn't too wet with a lot of spring to it.

a great addition to the quark line

There are two primary differences from the previous version. The threads have been upgraded to the Acme style, which makes capping and posting much faster and easier.. The second change is that the material is shinier. This is a great pocket pen.
