Use & Precaution 

Natural stones vary from synthetic stone in that they do not require any soaking, but do require slurry formation via the use of nagura stones or diamond plates. If you use less water on the stone, it will cut faster but have a coarser finish.

Do not also soak in water finishing stones #3000 and above. After use, let the stone dry thoroughly. Returning a stone into its box while still wet or damp will result in molding and might decrease in quality.

It usually takes 1 –2 weeks for us to restock should this item is not available.
