PURELINE Oralcare Moldable Bleach Trays for Opalescence Whitening Teeth - 3 Tray

Useless don’t waste your money

Not good

Do this and they will work!!!!1. Put a cup of water in the microwave for 2 minutes— the water should be steaming, but not quite boiling. You should be able to put your finger in it and it should feel pretty hot.2. Submerge the tray in the water by holding the tab for about 5 seconds. You should see the tray curve inwards on itself by the ends, this suggests it is capable of being molded.3. Immediately place the tray in your mouth and PRESS ON THR FRONT OF YOUR TEETH with your fingers. This will give you the mold to your teeth.4. Keep the tray in your mouth for 3-ish minutes while it cools.5. Trim the tab and excess gum space you don’t need.6. Add whitening gel and enjoy!!This is what worked for me on the first time, first tray. I hope it works for you! 5/5 stars! I am using with Opalescene.

I did everything and followed the instruction, and it wasn't working at all. Don't waste your money on it.

This was total crap. Did not come with directions so I googled for help. Still total crap and a waste of money. No refunds or offers for a refund or replacement. I thought since it had the opalescense name it would have worked. Wrong…🙄
