Xcaret Artesanal Feria is a marketplace where you can find authentic molcajetes, traditional Mexican stone tools used for grinding spices and other ingredients.
One option is a small molcajete that costs around $800 pesos, which is a good price considering the quality and craftsmanship of the item. The feria is worth visiting even if you're not looking for a molcajete, as it offers a variety of traditional Mexican goods and souvenirs.
