This is a small-sized suribachi (mortar). I will not be measuring the size. It's the perfect size for grinding sesame seeds and spices, making sauces, powdering medicine, and preparing baby food (^^) It's also convenient because it's microwave and dishwasher safe! Size: (approx.) 10cm in diameter Condition: New, unopened Please note that we are not responsible for any damage during shipping. Price reduced!
