Idento Pocket Brush is for people with slightly larger gaps between the teeth. Pocket Brush is like a "bottle brush" with a small brush, which gently cleans between the teeth. We designed the Pocket Brush so it can be pushed up from a holster and after use can be pulled down in the holster again. This means that the Pocket Brush can be placed in your pocket. The Pocket Brush can be found in three different sizes marked with three different colors.
