This was one of the products I picked up in the vault. I am definitely always after a whiter smile so was so stoked that I was able to get a pottle.
The pottle has a screw top lid and a little stopper lid inside to ensure you don't scatter the product all over your bathroom counter. To use you wet your toothbrush, (I made sure I used a separate toothbrush for this) dip it into the powder, tap off the excess, and brush with your mouth closed. The powder has no real noticeable taste to it so you do really miss that minty freshness that a toothpaste gives you. I find that I can never quite rinse all of the product off my teeth afterwards, so have to follow with my usual brushing routine with toothpaste. This is a little abrasive so really gets all the gunk off your teeth, leaving them feeling way cleaner than a regular toothpaste can. I didn't particularly notice any whitening effects just a really clean feel and look to your teeth.
While I do like the way this makes my teeth feel afterwards I really hate the process. You end up with mess all over your sink, all over your clothes and lips. In addition if you have to brush your teeth again afterwards it really does make the whole brushing process quite lengthy- who has time for that twice a day! Because of this I only use this product once or twice a week, almost like an exfoliation for my teeth (that sounds gross but if you felt how clean this made your teeth feel you'd get my drift). I still need to use a whitening pen in addition to this on a weekly basis. Because of the irregular use this little pottle is going to last forever!
