Starting out in aesthetics can feel overwhelming, especially when learning to master fillers. However, incorporating Ka Rings into my practice has been a game-changer. They’ve made the process of aspirating simple and stress-free, giving me the confidence to focus on delivering great results. Highly recommend!

Great product!

Loving this new design! Got one at the Aesthetic Next conference and ordered 4 more for the office a few days after we arrived home. The shipment arrived and to my surprise they had updated it a little. The feet on the bottom makes sure the product is not going to move! Love these new additions!

Thank you so much Emily! It was such a pleasure to meet you at Aesthetic Next and we're thrilled to get such wonderful feedback on our new Offical Tox Spot release -- Thank you!

Awesome device!

Love this new device and I love the personal note that came along with my order!

Thank you Christina! This is a very personal endeavor for us, and it means the world to have your support!

Fantastic product, a must have device that makes life easier and safer

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.

Thank you for your thoughtful feedback Tim. We’re thrilled to hear such a compliment—that’s exactly what we aim for. Your recommendation means so much, and we’re honored to be a part of your practice!

Excellent customer service!!!

I had ordered a set of rings, but I am in Canada, and I believe that the syringes up here may be slightly different than in the United States. As a result, my ring didn’t fit my syringes, But the team was quick to resolve the issue and sent me the correct rings! Amazing customer service, and now I have the right product!

Thank you for taking the time to share your concerns, and I'm really sorry to hear that you're having trouble with the device. It sounds like there might have been a little mix-up with the syringe model. Our device is designed specifically for the newer RHA models with a rubberized plunger, and it looks like this might not be the best match for the syringes you have.

We've already reached out via email to help sort this out. We'd love to offer you a full refund and get the right product to you—one that fits perfectly. Your safety and satisfaction are super important to us.

Please do check your inbox when you have a moment. We’re here to make sure everything is sorted out to your satisfaction.

Looking forward to hearing from you!

Great, really useful

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

Thank you for sharing your experience! We’re so glad our Control Ring has been a valuable addition to your practice. It’s designed to support injectors at every stage, and we’re honored to be part of your journey! :)

The control ring is amazing and helps immensely! Love love love it!

If you’re not aspirating you’re injecting wrong!

I absolutely LOVE every single control ring I have! It has seriously changed my injectable game! I have feel like the rings allow me to have so much more control over my needle and plunger now! Where before I would shake like crazy! I aspirate with ease now! I randomly stumbled upon KA designs on a FB group and I’m soo glad I did! If you’re not using these in your practice, you’re missing out! They will have you injecting on a whole other level! Thank you David and Alyssa! I appreciate you all!

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.
