Review title is Excellent Product [SEP] I can't tell if my teeth are any whiter or not after using but I can tell that my sink and counter top are a lot darker.  It's messy.  But I still like it a lot.  The powder is very fine and not coarse, and has no flavor.  It think the activated charcoal is very good quality.  I use activated charcoal a lot but not so much for brushing my teeth.  I make handmade soaps and I like to make BLACK soaps because they are so cool looking and clean the skin so well.  I used some of this in some soap and it worked great!  The toothbrush is good and so is the tongue scraper though I prefer a larger tongue scraper.
