Display of a 30-piece pack of "Chiruchiru Michiru Micro Filter Pipe." These are mini pipes designed to reduce nicotine and tar. Micro silica attached to the special fibers inside the filter adsorbs nicotine and tar as the smoke passes through. Vitamin C and enzymes contained in the filter absorb harmful substances, making smoking milder. I used to run a tobacco shop. Although the packaging is faded, the contents are new and unused. Please refrain from purchasing if you are concerned about minor details. Thank you for looking.
