Every reusable PepPen takes a standard 3 mL glass cartridge and dials in 0.01 mL increments. The differences come down to build and how the cartridge loads. Here’s a straight comparison. Current prices are on each product page.
The quick version
| Pen | Best for | Cartridge loading | Max per press |
|---|---|---|---|
| V2 | Most people. Our most popular pen. | Open end | 0.60 mL |
| V2 Pro | V2 handling with a locking holder | Twist-lock | 0.60 mL |
| V1 | The most solid build in the range | Twist-lock | 0.80 mL |
| V3 | A classic V1-style look with updated internals | Open end | 0.60 mL |
| Disposable | One cartridge, start to finish, at our lowest price | Standard 3 mL cartridge | See product page |
PepPen V2: our most popular pen
The V2 is where most people start. It’s solid metal and our best seller. The cartridge drops into an open-end holder under the front cover, which makes loading quick.
PepPen V2 Pro: our pick
If you want one pen to recommend, it’s the V2 Pro. It keeps the V2’s handling and adds a twist-lock cartridge holder, so the cartridge locks in place. It also has an upgraded finish.
PepPen V1: the best build
The V1 is our original and still the most solidly built pen in the range. It uses a twist-lock holder and dials up to 0.80 mL per press, the most of any PepPen.
PepPen V3: the hybrid
The V3 pairs a classic V1-style exterior with updated internal components and an open-end holder like the V2. It dials up to 0.60 mL per press.
PepPen Disposable
The Disposable is built to use one cartridge from start to finish. It isn’t a single-use pen, and it doesn’t come prefilled. It’s our lowest-priced pen and a good option if you don’t need one you’ll keep for years.
