16 P Replacement 10Pcs

I am a licensed esthetician and this is my favorite needle cartilage size and brand. It connects to the sergaurd pen very easily. I love the fact its individually packaged for sanitation purpose and love the fact its labeled with the needle size for correct storage. Will definitely be purchasing again!

Original quality. They fit the Dr. Pen. No complaints, no pain, no gain.

Bought these to have extra pieces to use with pen I bought. Wanted more of the 36 needles to perform "cosmetic" microneedling procedures. Love that they come individually wrapped and sterile. Much easier and quicker than having to soak the roller devices in alcohol before and after each use.

I absolutely love my Dr pen M8 microneedling device. Microneedling has don't wonders for my acne prone/ aging skin. These fit perfectly and are well priced will buy again

I bought these because the description and reviews say it fits my Dr. Pen m8. But they didn't fit. There's another review with pictures of the same issue I had. The cartridge didn't slide down and lock in place. Very frustrating.

These work perfectly with the microneedling pen!

These work for my microneedle pen, but they are expensive and when you have a few malfunction, it becomes irritating. I have had three not work so far.

Work great at a fair price point
