💠 AUTHENTIC 10-PACK: Includes 10 individual 14-pin cartridges with a bayonet-style connection compatible with the Dr. Pen A20 device.

❤️ SINGLE USE ONLY: Use one new sterile cartridge for each procedure and dispose of it immediately after use. Do not reuse, reprocess, or share cartridges.

Important: microneedling cartridges must be sterilized before each use to ensure safety and hygiene. Follow these steps carefully to sterilize your microneedling cartridges:
1. Gather Equipment: Ensure you have gloves, a 70% or higher isopropyl alcohol solution, and a clean container.
2. Wear Gloves: Put on gloves to avoid contaminating the cartridges.
3. Inspect Cartridge: Ensure needles are in perfect condition and free of debris.
4. Sterilize:
- Dip Method: Pour alcohol solution into the container and soak the cartridge needle for a few minutes.
- Spray Method: Spray alcohol solution directly onto the needle head of the cartridge.
5. Air Dry: Allow the cartridge to air dry completely before use.
Your cartridge is now ready for use.
