Game changing product

I've tried a few of these types of devices, and usually they are awkward and distracting to use. Constantly adjusting them is a distraction.

The best compliment I can give, is that I only think about the k ring when it's not there.

Every injector should use these for safety and convenience.

Worth it

I am an injector and it’s very difficult for me to aspirate. I have small hands and am still new to injecting. Worth every penny will keep them in stock

Love RHA & KA rings!

My favorite filler is RHA. First time applying KA rings to the syringe and I was in love! The ease and user friendly of the product is amazing. Thank you! I love using a product with patient safety the top priority.

Love the rings!

They were super easy to use. Took a little bit of getting used to at first but once I did they were comfortable and no issue
