Big Maks Hookah Bowls are clay bowls made in Russia. The bowls are made from a mix of clay and sand, and they are fired in a kiln to give them durability. The bowls are then glazed with a food-safe glaze, and they have fired again. This process gives the bowls their smooth, non-porous surface, which is perfect for hookah use. Big Maks Hookah Bowls are a great way to enjoy hookah smoking, and they make a great addition to any hookah collection.
