Shine Whitening Extra Large Peroxide Refill Kit (4) 5cc Syringes (Whitening Gel Only) 36% Carbamide Peroxide

Gel Directions:

First apply around .05 cc to each arch (which is roughly one small drop) along the inner facial side of both the upper and lower arches. Make sure to spread the solution evenly with a syringe tip. Be careful not to overload the tray. You can also use a Q-Tip to apply the solution directly to your teeth, to ensure the solution does not touch your gums.
Once the surface is evenly coated, wear in your mouth for 5-15 minutes per day. If you have no sensitivity, you can use this on consecutive days. If you have slight sensitivity, it is recommended that you wait a few days between treatments. Once done wash your mouth with cool water. Do not swallow any of the gel. Repeat as needed until desired shade is achieved.
