Microneedling Pen Cartridges For Microneedle Machine Set (10 PCS 36pin) US-36-J114

I was skeptical cause I did not know if the gauge was correct but it was it works really well with my micro needling pen.

Perfect fit for my pen , nice quality . Easy to use and dispose of .

Good

Good cartridges. Just like the ones that came with my device.

Very satisfied with purchase, sellers pictures were very helpful to select correct size. Fast delivery and I liked that I could buy all same size needle in package of 10

I purchased this product based on the reviews I read. Please do not purchase. The cartridge is totally different from the brand versionThe part of the cartridge that should be fastened and locked into the pen is shaped in a circle , on the pen the Parr is rectangle . The original cartridge has a circular downward pattern to help lock the cartridge into the machine on the replacement cartridge there's no ridges it just slides down so it doesn't fit in no way shape form or fashion. I tried to alter the circular piece to make it fit by filing, burning and reshaping the plastic in an attempt to change the shape to a rectangle to fit it doesn't work the entire cartridge does not fit into the machine it's a waste of money for product that can't be returned or used. Buyer beware!

On some of the cartridges, the threads, that allow you to screw the cartridge into the pen, are off and the cartridge ends up sitting crooked in the pen.

The item was fine but it was the wrong cartridge for me
