Dr. Pen Ultima M8 Replacement Cartridges - (20 PACK) - Round Nano Bayonet Slot - Disposable Replacement Parts

Love these!

These work great and we’re definitely designed for my dr pen m8. Love using these in between my micro needling with the longer needles

I absolutely love these. I bought both the nano and microneedle cartridges and they are perfect. Very well made and individually wrapped for sanitary purposes. This is my go to for cartridges for my M8 pen.

These are great to use frequently to really get whatever serum you’re using into your skin.

I love using these nano cartridges with ya PDRN serum. My face feels so smooth and a overall better look. I even have to use less foundation.
