These pre-sterilized, single-use cartridges provide a consistent 0.25 mm needle depth and a 36-pin configuration engineered for even coverage during routine microneedling sessions. Designed for easy attachment and removal, they are intended as replacement tips for compatible Dr Pen models, delivered in a pack of ten to support multiple treatments while keeping hygiene front of mind.

How do these cartridges fit my Dr Pen device?

The cartridges are manufactured to click into the compatible Dr Pen M8S, A8, A9 and A11 housings without modification. Each cartridge uses the standard bayonet-style connection common to those models, enabling quick swaps between sessions.

• Compatible with Dr Pen M8S, A8, A9 and A11 models
• Push-and-twist or bayonet connector for secure seating
• Designed for tool-specific alignment and stable performance
• Single-use disposables to minimize cross-contamination risk

What does the 0.25 mm needle length and 36-pin layout mean for use?

A 0.25 mm length is a shallow setting typically chosen for surface-level work such as improving skin texture and product absorption; the 36-pin arrangement gives broad, even contact across the area treated. The configuration supports uniform coverage while remaining gentle for at-home routines.

• 0.25 mm depth for superficial, surface-level sessions
• 36 pins create wider coverage with fewer passes
• Consistent pin spacing for uniform results across the skin
• Suitable for delicate facial areas where a lighter penetration is preferred

How should I handle and store these cartridges safely?

Each cartridge is packaged for cleanliness and intended for single use; once removed from its sterile packaging and attached to the pen, it should be discarded after the session. Store sealed packs in a cool, dry area away from direct sunlight and out of reach of children until ready to use.

• Keep cartridges sealed until immediately before use
• Use one cartridge per session and dispose responsibly afterward
• Store in a cool, dry place to maintain sterility before opening
• Follow the device manufacturer’s guidelines for cartridge disposal

How many cartridges are included and what scenarios are they best for?

This set contains ten 36-pin cartridges, suitable for multiple short sessions or for keeping spare tips on hand. The pack size works well for users who perform routine maintenance, trial different prescriptions of topical products, or want a fresh sterile tip for each appointment.

• 10 cartridges per pack for repeated at-home treatments
• Ideal for users who schedule regular surface-level sessions
• Convenient for travel or to keep a hygienic supply at home
• Good option for people who alternate pen heads by treatment area
