kopcesw Microneedling Pen Cartridges 36‑Pin 0.25mm — 20‑Pack for M8/M7S, Single‑Use Presterilized

These are 20 disposable 36‑pin microneedling pen cartridges (0.25mm) designed for easy, at‑home use with kopcesw‑compatible M8 and M7S derma pens.

Designed for people who already own a compatible derma pen or are shopping for replacement heads, these cartridges provide a compact cluster of 36 tiny needles at a fixed 0.25mm depth. They are single‑use, presterilized (packaging dependent) replacements that snap onto M8 and M7S style pen housings, offering an economical supply for routine microneedling sessions at home. The small needle length keeps sensations milder than longer cartridges while delivering consistent surface stimulation.

How do these cartridges connect to my M8 or M7S derma pen?

The kopcesw cartridges are engineered to fit the snap‑in or twist‑lock mechanism used by M8 and M7S pen models. Installation is straightforward and requires no tools—just align, press, and lock. Always confirm compatibility with your specific pen model before use.

• Made for M8 and M7S mounting systems
• Push‑in or twist‑lock attachment depending on pen design
• Single‑use cartridges to prevent cross‑contamination
• Clear visual alignment markers on most packages

What does the 36‑pin, 0.25mm specification mean for at‑home sessions?

A 36‑pin head contains a compact array of fine needles that treat a broader surface area per pass than single‑needle cartridges. The 0.25mm needle length targets the superficial layers of skin, making it a common choice for maintenance routines and gentle surface work. It’s suited for users who prefer reduced downtime and milder sensation.

• 36 needles for efficient coverage with each stroke
• 0.25mm length for gentle, superficial stimulation
• Designed for frequent, maintenance‑style sessions
• Uniform needle placement to help consistent results

Are these cartridges safe and easy to use at home?

They are intended as disposable, single‑use heads to limit contamination risk when used with proper hygiene. While designed for home users, correct cleaning, skin preparation, and aftercare are essential. If you are new to microneedling, review instructions and consider consulting a professional before starting a routine.

• Dispose after one use to maintain hygiene
• Follow your pen manufacturer’s instructions and local guidance
• Use antiseptic protocols before and after treatment
• Not recommended for broken or irritated skin

How many sessions will a pack last and what’s included?

This set contains 20 individual cartridges, giving you many sessions depending on treatment frequency and whether you use one cartridge per session. Many users replace the cartridge each time; others reserve fresh heads for facial zones or single‑area treatment to maximize supplies.

• 20 disposable cartridges per pack
• One cartridge is commonly used per full face or multiple smaller areas
• Pack reduces the need for frequent reordering
• Check packaging for sterilization and storage guidance
