Solid Rustproof Material: mortar and pestle are made of food grade 18/8 stainless steel. Not only is it rustproof, it is also resistant to damage and corrosion by acidic food.
Durable and Stable: Made of solid metal, the pestle feels substantial in your hand and the mortar sits unbudgingly on your kitchen counter. Padding on the bottom makes it stay put even more.
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.
