Summary:A toothbrush handle comprising a terminal end a connector end an outer surface an inner cavity and a longitudinal axis. The inner cavity has a surface defining a cross sectional area. The inner surface has at least one of a greater cross sectional area bordered by two lesser cross sectional areas along the longitudinal axis or a lesser cross sectional area bordered by two greater cross sectional areas along the longitudinal axis. The outer surface defines an outer surface cross sectional area. A wall is formed from the outer cavity surface to the inner cavity surface. The toothbrush handle comprises a single unitary component. The difference between the outer cross sectional area and the inner cavity surface cross sectional area varies less than 25 % over at least 50% of the toothbrush handle length along the longitudinal axis.
