Thanks to the practical packaging, the filters can now be transported without any problems, as the filters can be stored in an airtight and watertight manner and are thus protected from external influences. The use of the activated carbon filters significantly reduces the absorption of pollutants and provides a cool, dry and aromatic smoking experience, which is also good for your health. Suitable for standard 9 mm pipes & of course for ALL types of hand-rolled! Since both end caps are ceramic, there is no insertion or twist-in direction to consider.
