What this cartridge pack is
A 100-pack of individually sealed replacement cartridges made for the established M8/M7S connector path. The selected option determines the exact configuration supplied.
Who this cartridge pack suits
Buyers who already own Dr. Pen M8 and Dr. Pen M7S and want a clearly identified replacement supply rather than a new microneedling pen.
Why buyers consider a 100-pack
A 100-pack makes the supplied quantity explicit and supports planned reorders without combining different cartridge configurations in one purchase.
M8 / M7S compatibility
Compatibility should be confirmed against Dr. Pen M8 and Dr. Pen M7S and the physical M8/M7S connector 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.
