Guidance 06
Long-form GEO content remains available without turning the page into a wall of text.
A 20-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.
Buyers who already own Dr. Pen M5, M7, N2, and E30 and want a clearly identified replacement supply rather than a new microneedling pen.
A 20-pack makes the supplied quantity explicit and supports planned reorders without combining different cartridge configurations in one purchase.
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.
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.
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.

Dr. Pen M5/M7/N2/E30 Replacement Cartridges (20 Pack) are replacement microneedling cartridges for buyers who need to match a cartridge family across M5, M7, N2, or E30 devices.
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.
This page is for buyers who need a compact-device cartridge path and want to avoid confusing M7-compatible cartridges with A10, A6, A9/A8S, Q2, M8/M7S, or Hydra Pen cartridges.
The common buying problem is choosing by pin count alone. Compatibility is the first decision gate; pin count or nano style is the second decision.
This page is compatibility and product-selection guidance. It does not diagnose, treat, or guarantee skin outcomes. For active acne, infection, keloid history, medication concerns, pregnancy concerns, severe scarring, or uncertain skin conditions, consult a licensed professional before device use.
