These premium polished whisky stones measure approximately 20 × 20 mm and are sold loose (not boxed), ideal for engraving or custom packaging. Made from soapstone or granite, the non‑porous, tasteless stones cool whisky and spirits without diluting. Great for engraving with initials, monograms, or logos—perfect as retail items, refill products, or part of custom gift bundles. Supplied in cartons (500 pieces) to support bulk or trade purchases.
