excellent product [SEP] i cannot 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 is 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
