Mini mortar and pestle set. I've used it a few times to crush pills. After that, it's been stored at home without use. It's in very clean condition. Material: Porcelain - body and pestle Size: Diameter 7cm (inner diameter 5.5cm) Height 4cm Pestle: Max width 2cm, length 7.5cm Main Uses: Pharmacy: Grinding raw materials for Kampo medicine and tablets into fine powder. Japanese Painting: Crushing pigments like "suisai" and "gofun" (white pigment) to adjust the paint (dry grinding). Cooking: Grinding herbs and spices to bring out their aroma (enjoying a deeper aroma than with a pepper mill). Design: The inside of the mortar doesn't have grooves like a regular mortar. It's rough. Stored at home. Please understand and purchase accordingly. Mortar Pestle Mortar Pestle Porcelain
