The gel has a transparent structure. It contains some abrasive material for better cleaning of tooth enamel. Enamel does not hurt, does not irritate the gums, it tastes nice, foams well, economical consumption, after cleaning there is a short-term sense of viscosity in the mouth. On IHERB a lot of good toothpastes, gels. I would like a lot to evaluate, so the re-purchase of the gel is not assured. Although no complaints to him there.
