Maruichi was old company that sold barber supply, they are mostly associated with Nakayama Stones and even owned Maruka stamp
However they did cary many other stones as well Hakka Shoubudani Hideriyama ozuku etc.. And stamped them also with Maruichi stamp
Here is one example of that, Hakka Suita
Amazing full size Hakka as it is softer stone all those lines Can not be field at all, it is on finer side but still soft and super easy to use
Make that amazing sandblasted like Kasumi finish ! Light and super beautiful colour
Very rare stone now !
Size: 205mm 75mm 35mm
