Three Kings' Quick Light charcoal is disc-shaped and available in two sizes, measuring 33 mm or 40 mm in diameter. The tabs can be used for smoking shisha or for burning incense and ignite much quicker (what's in a name) than other charcoal tabs on the market. This makes them highly convenient and easy to use. The tabs are made of 100% European beech wood and are odorless. They have a smooth, long and even burn, and produce very little ash ' offering a consistent quality level. Make sure to store the charcoal tabs in a dry place.
