What this cartridge pack is
A 50-pack of individually sealed replacement cartridges made for the established M8S/A8S/A9/A11 three-slot cartridge path. The selected option determines the exact configuration supplied.
Who this cartridge pack suits
Buyers who already own Dr. Pen M8S, A8S, A9, and A11 and want a clearly identified replacement supply rather than a new microneedling pen.
Why buyers consider a 50-pack
A 50-pack makes the supplied quantity explicit and supports planned reorders without combining different cartridge configurations in one purchase.
M8S / A8S / A9 / A11 compatibility
Compatibility should be confirmed against Dr. Pen M8S, A8S, A9, and A11 and the physical M8S/A8S/A9/A11 three-slot cartridge path. This product is not presented as a universal cartridge.
How to compare pin counts
Pin count is a product configuration, not a universal treatment recommendation. Buyers should select only after confirming the intended cosmetic-use plan and device instructions.
How nano cartridge types differ
Nano Round, Nano 5D, Nano 3D, and Nano W are kept in a separate family so non-needle surface patterns are not confused with microneedling pin counts.

What this product is
Dr. Pen M8S/A8S/A9/A11 Replacement Cartridges (50 Pack) are replacement microneedling cartridges for buyers who need to confirm model compatibility before choosing pin count or restocking cartridges.
Compatible devices
This cartridge listing is for the M8S/A8S/A9/A11 cartridge family. Before ordering, match the cartridge family to the exact model printed on your pen. Related device pages include Dr. Pen A9, Dr. Pen A8S Pro, Dr. Pen M8S, and Dr. Pen A11.
Who this product suits
This page is for buyers who already own or are buying a compatible M8S, A8S, A9, or A11 device and need a replacement cartridge path without mixing it up with A10, A6, A1, M7, M8, or Q2 cartridges.
Why buyers consider it
The common buying problem is cartridge mismatch. A cartridge can have the right pin count but still be wrong for the device if the cartridge family does not match the pen model.
What to check before buying
- Pack size: 50 replacement cartridges.
- Compatibility gate: confirm M8S, A8S, A9, or A11 before selecting a variant.
- Variant options on this listing: 12 pin, 18 pin, 24 pin, 36 pin, 42 pin, and Nano Round.
- Routine planning: choose replacement cartridges by device model, intended area, comfort, and product instructions.
- Risk variables: use a fresh compatible cartridge, avoid reuse, do not mix cartridge families, and do not assume pin count alone determines compatibility.

Questions to check before buying
