Review on 🦷 Meyarn 2PCS Teeth Whitening Gel Pens with 35% Carbamide Peroxide - Non-Sensitive Teeth Whitener and Whitening Gel Pen by Toledo Barringer

If this gel is really 35% carbamide peroxide then it's DOUBLE what the old tube of bleach my dentist gave me! to see how much carbamide peroxide was in it: 16%. I've used it with custom trays that were expensive. And also those 2 pens for $13.99 and double the price? Well! The gel is squeezed onto the tip of the brush and you apply it to your teeth. The difficulty lies in stopping it for 15-30 minutes. without swallowing any of it. I used it 3 nights in a row and you know what? I see enlightenment! I'm a coffee drinker and I use whitening toothpaste and conditioner to get rid of coffee stains, but this gel is on another level. use to make it easier. I will use 1 pin and then compare to my "before" picture to really see. Something seems to have changed in the meantime.**Thank you for reading my review and I hope it was helpful!**
