Perfect Microneedling Replacement Cartridges
These cartridges fit the Loutsbe brand Microneedle Instrument that I purchased from Amazon. After much research, I was so happy to find these as it seems there are many different types out there. It can be rather confusing finding the correct cartridges. The quality of these is excellent and they screw in perfectly. These have the treads above the little spring.

Micro needling replacements
These cartridges all came well sealed, and well aligned so when I use them, they don’t stab deeper in one spot than the other and they fat my micro needling pen.
