I have looked for these for years, and have never been able to find them until now. Curved handled 19th century toothbrushes. These are vintage brushes from France and are NEW and unused. They aren't cheap and weren't cheap for me, but it's the only place I'm aware of that you will find a curved handled 19th century toothbrush for your kit. The handles are made from bone and the bristles are genuine boar bristle. We, as far as we know, are now the only consistent source for this item! Some have bristles with curved handle that curves downward and some have bristles and then handle curves upward.
