Simpsons M7 sovereign synthetic shaving brush. The M7 is one of the original Alexander Simpson brush designs dating back to 1919. As such, the handle is synonymous with the shaving community. It is a brush handle replicated by other manufactures many times, but never bettered! This variant of the M7 comes densely filled with Simpsons uniquely sourced, sovereign grade synthetic fibres in an large imitation ivory handle. Possibly the ultimate bowl lathering brush. Handmade in Great Britain.
