These are natural stones I collected in the past at the Hime River Jade Coast in Itoigawa and the Jade Terrace in Toyama Prefecture. The characteristic of Himekawa Yakuseki (Himekawa Medicinal Stone) is that it has many holes on its surface. It is said that putting it in the bath improves blood circulation and promotes health. The weight was measured with an old measuring instrument, so the weight of 1.2kg is only an estimate. I have seen them sold commercially for 4 yen per gram, so I set the price accordingly. The stones for sale are unused. For more detailed information on the effects, please search for "[Himekawa Yakuseki Effects]".
