Great whitening pen
Enjoy the ease of using these pens. The product is applied by twisting the tube several times until the product shows on the brush tip. Each tooth is brushed with the product and then allowed to dry for 30 seconds. An easy way to keep your teeth their whitest. My teeth whiten a level with each application so if itsl been a while, I'll use it several days in a row for best results.
