This is a set of 3 toothbrushes for final polishing. It's a one-tuft type with a conical shape that can brush even the smallest gaps. I was recommended to use a one-tuft type by a public health nurse, and I had stocked them for polishing my child's teeth, but I'm selling them because my child has grown and no longer needs them. They are new, unused, and unopened, but the cases are dented in a few places due to home storage (photos 5-6). Please understand. - Colors: Pink, Blue - Type: Soft - Quantity: Set of 3 - Purpose: Children's toothbrush Thank you for looking.
