This is a 4 pack of The Plaque Buster Large Canine Dental Tool Plaque Remover & Gum Stimulator for Dogs. Colors may vary. It's an innovative, one-piece, injection-molded design with no metal to cut the gum or scratch your teeth. I am the original inventor and manufacturer of this patented product. If you are buying it from anyone else on eBay or Amazon then you are not buying it from the source. Message me if you have any questions. I am always happy to connect. Tags: Toothpick, Interdental, Gum, Teeth Supplies, Dental Floss & Flossers, Dental Scaler, Gum Stimulator, Plaque Remover.
