These work! I saw other reviews saying they didn't fit because they have a small round connector and that's what they have. Look inside your pen, I have an off brand pen and used my phone flashlight to look to see how it connected inside and it's round. It's also threaded so the product is described well and fits my no brand pen. Great price as well, I found the same ones on eBay for double the price. Very happy with this purchase and will be buying again.

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.
