Pure Smile Teeth Whitening Pen is an easy to use pen which only takes 60 seconds twice a day and whitens your teeth up to 1-3 shades brighter. The pen lasts about 30 applications! The best part is that its an all-natural product, gentle and effective. I noticed an improvement after a week. Teeth whitening can't get any easier!
