Condition
- Stone: Sold in two states, selectable above. New stones are unused and factory-fresh. The Used stone has been sharpened on and is priced accordingly; it is flat, sound, and has plenty of life left.
- Packaging: While our inventory is new, the original packaging may show minor shelf wear, scuffing, or external softening due to warehouse storage and handling over the last five years. Internal protective wrapping (plastic or paper) may show signs of handling, minor tears, or may occasionally be absent—this never affects the condition of the stone itself.
Shipping
Orders are typically processed and shipped same day from Santa Maria, CA.
Every stone ships in a new, high-quality box, individually wrapped in bubble wrap and packing paper for maximum protection in transit.
