What this cartridge pack is
A 30-pack of individually sealed replacement cartridges made for the established M5/M7/N2/E30 cartridge connector path. The selected option determines the exact configuration supplied.
Who this cartridge pack suits
Buyers who already own Dr. Pen M5, M7, N2, and E30 and want a clearly identified replacement supply rather than a new microneedling pen.
Why buyers consider a 30-pack
A 30-pack makes the supplied quantity explicit and supports planned reorders without combining different cartridge configurations in one purchase.
M5 / M7 / N2 / E30 compatibility
Compatibility should be confirmed against Dr. Pen M5, M7, N2, and E30 and the physical M5/M7/N2/E30 cartridge 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.
