Review on Pureline Oralcare 4 Thermo Molding Custom Fitting Whitening Trays: Achieve Your Brightest Smile! by Stephanie Hammons

So I went to my dentist and bought a set of Opal Essence teeth whitening syringes and have been looking for a mouthguard to use with them ever since. I didn't want to spend more than $300 on custom ones and this was my alternative. I never knew it even existed until I looked here. came and works fine. I boiled water and dipped them in one by one until I saw them getting brittle, I just let it cool for a second and then made my molds. I trimmed them a bit and they were ready to go. My first whitening went smoothly, they fit my mouth just right (not on their own but with a gel), they weren't thick at all, they came packaged in an envelope in the box they came in and with precise instructions! I AGREE TO THIS PRODUCT!
