Conversion Stone Set of 3 w/ 1 of each .375, .500 & .625

The Conversion Stone is made of a special, high-quality glass built to last and thermal shock resistant. The stone is reusable by a self-cleaning design. No cleaning solution needed just torch the stone back to white.

The filtration reduces toxins by filtering particles, impurities and tar related to smoke, butane and hookah charcoal. This reduction filtration design results in a healthier smoking environment with clean smoke being ingested by the smoker and secondhand smoke. As a result, the filtration helps retain the flavor and taste of the tobacco.

The conservation design allows for low heat (single torch lighter, hemp wick or a traditional lighter), heats fast, and retains the heat. As a result, the conservation saves time and butane. The stone blocks particles where tobacco is not being orally sampled or wasted.
