Many are made from marble; some combine marble with wood elements, and a few are cut from granite.
Listings commonly describe unpolished or coarse interior surfaces, tall or rough-walled bowls to aid grinding, and heavy, comfortable pestles that let you apply pressure without ingredients escaping.
Descriptions note solid, heavy construction—often cut from one piece of stone or solid marble—built to last without easily breaking or cracking; reviews also mention a sturdy, well-made feel.
Diameters and bowl sizes tend to cluster in the small tabletop range (about 3.75–4.5 inches diameter) with heights around 1.5–4 inches. Listed capacities range from a few dozen grams up to several ounces (examples: 44 g, 1–3 oz, up to 8.47 oz).
Care instructions typically recommend hand washing or spot/wiping with water and mild detergent. A few listings include the warning: do not microwave.
