Loaded From Day One

Most first orders arrive half finished. The pen comes, the cartridges are a separate order, and an aluminum instrument sits in a drawer waiting on a second package.

This kit has both. One V2 pen in the finish you choose, and ten sterile 3mL cartridges. Fill one, drop it in, and you're working the day it lands. Nothing else to order.

0.01 mL per click, felt rather than read.

Squinting at graduation marks on a syringe, in bad light, hoping it matches last time. That's the part the dial removes.

Sixty click stops, each one a fixed step in the mechanism.

Ten cartridges is a shelf, not a sample.

Ten 3mL steam sterilized cartridges, sealed one per pouch with a steam indicator on each,

That's 30 mL of capacity, about fifty full turns of the dial, sitting on the shelf before you think about reordering.

FAQs

Please read our FAQs page to find out more.

Does the pen comes with a cartridge?

No, the pen and the cartridges are separate purchases, and you'll need at least one cartridge before the pen does anything. We sell them in 10 and 20 packs, steam sterilized and individually sealed.

If this is your first pen, take the 10. After a month you'll have a much better idea what you actually go through, and the 20-pack will still be here.

V2 or V3 — which one do I buy?

Whichever one you like the look of. They're mechanically identical: same 60-click dial, same 0.01 mL per click, same cartridge.

The V2 is the cheaper of the two. There is no "more accurate" model, so you're not trading away precision either way.

Do I have to refill it before every session?

No, and that's the whole point of the pen. You fill a cartridge once, drop it in, and every session after that is dial, dispense, done. The filling step happens once per cartridge instead of once per session.

New pen feels stiff. Is it faulty?

Almost certainly not. That's the mechanism bedding in, not a fault, and a brand-new pen tested this way looks broken when it isn't. Resistance is the sum of several things and they stack — a fine tip on a cold, slightly viscous solution feels far worse than either problem alone.

Do you sell pen tips?

No, we do have recommendations over at the Pen Tips page.

The pens take standard universal screw-on pen needles, available anywhere they're sold. Fresh tip every session.

Does it come pre-filled?

No. Pens and cartridges ship empty. It dispenses whatever you put into the cartridge, at the amount you dial, and it has no opinion about what that is.

How fast does it ship?

Orders process in 1 to 2 business days from U.S. fulfillment centers, tracking emailed automatically, plain box.
