Product identity

Compatible device path
This cartridge listing is for the M5/M7/N2/E30 cartridge family. If you are buying for Dr. Pen M7, confirm the M7 model name before selecting a cartridge variant.
Best-fit audience

- Variant options on this listing: 9 Pin, 12 Pin, 24 Pin, 36 Pin, 42 Pin, Nano Round, Nano 5D, Nano 3D, and Nano S.
- Routine planning: choose by model compatibility, intended area, comfort, and product instructions.
- Risk variables: use a fresh compatible cartridge, avoid reuse, and do not mix cartridge families.
