Kolos hookah bowls have an original design that makes them stand out from other hookah bowls on the market. Each bowl is handmade and covered with glaze by hand, which gives it a unique appearance. The glaze is used by German manufacturers and is made from white and red clay. The clay undergoes a process called "milking", which improves water permeability and gives the bowl a characteristic shade. Kolos hookah bowls are known for their quality and durability, and the company's focus on customer satisfaction. If you're looking for a hookah that will give you a great smoking experience, then Kolos is the way to go.
