Price is negotiable! ☺︎! Mari Shiokawa Katakamuna Earthner Silica Sand (silica sand) I have two, so I'm selling one. ☺︎ Since the beginning of this year, I've purchased a new bag and replaced it. ☺︎ This silica sand is natural, domestically produced silica sand sold by Toyoura Keiseki Mining Co., Ltd., and is high-purity and high-quality. ☺︎ #KatakamunaEarthner #Crystal #Quartz #Quartz #SilicaSand #SilicaSand #Silica #Katakamuna #Osamu Maruyama #ElectromagneticWaves #Kusuri-e #Kusuri-e
