SOLID RUSTPROOF MATERIAL: Both pestle and mortar are made of food grade 18/8 stainless steel. Not only are they rustproof, it is also resistant to damage and corrosion by acidic food. Small compact mortar, about the size of the average palm – whereas one could pick it up with one hand, capacity 250ml
DURABLE AND STABLE: Made of solid metal, the pestle feels substantial in your hand and the mortar sits securely on your kitchen counter. Padding on the bottom makes it stay put even more.
FOOD-SAFE: Because stainless steel does not hold residue or leftover odor, all it takes is a thorough rinsing under the tap to get it ready for next use.
