Sure. I have 1 variety right now. Ingredients: Calcium Carbonate, Xylitol, Baking Soda, Sea Salt, Kaolin Clay. The sea salt is Redmond Real Salt Sea Salt that I grind to a smaller size to reduce abrasiveness. It tastes like salt because I wanted only active ingredients, no flavors added. It is a powder. I just wet the brush, knock off the excess water, and dip the brush in the powder. Any powder that gets wet sticks so the tin doesn't end up wet unless your brush is dripping. Otherwise brush as normal. Any specific questions?
