The site and box have very different instructions for use...
This is a 2 pack whitening brush pen. You twist the bottom of the pen and the product comes out of the top. It’s really quick and easy to use. It has a minty flavor but it’s not too strong and there are no whitening chemical aftertaste. The labels were peeling off the pens right out of the box. The directions on the Amazon site don’t match the directions on the box AT ALL. You’re supposed to brush your teeth first, dry off your teeth and then distribute the product. The site says to leave it on for 15-20 min and then rinse. The box says to leave it on for 60 seconds and doesn’t say anything about rinsing. These are 2 very dramatic differences. I’ve only used this once so far at haven’t seen any more difference than using a whitening toothpaste. I’ll continue to use it and update if there are any improvements.
