"Unglazed Mortar" Diameter: Approximately 21 cm "Volcanic Stone Pestle" Length: Approximately 11 cm Maximum thickness: Approximately 7 cm This is a souvenir from an overseas trip. The mortar has a coarse texture, so it seems to be for crushing rather than grinding. It seems suitable for making salsa or guacamole. Stored on a kitchen shelf. There are no smokers or pets. If you understand the condition, Thank you.
