Abstract
This article has two bundles of bristles (hair bundles) that are planted upright in a cylindrical shape in the center of the head portion of the handle, and six more bundles of bristles surrounding each of these bundles. The six more bundles of bristles are planted in a roughly trapezoidal columnar shape with a roughly trapezoidal base, at positions corresponding to the vertices of a roughly hexagon with the central upright bristles at the center.
