Used to make the packing tubes (or sleeves) individual cigars are packed and shipped in. Cellophane is made from cellulose and is microscopically porous. Cellophane will absorb moisture and therefore, cigars packaged in a cellophane sleeve will become moist or dry out to the level of humidity they are stored in. Store cigars with the cellophane on or off? This is a highly controversial subject. I’ll just say it’s a matter of opinion.
