The support (1) consists of a truncated conical sleeve (2) made from an impermeable material that will degrade in water, with an inner lining of non-woven fibres, preferably based on cellulose and glucides. It is preferably between 2 and 5 cm long, with a neck (4) at the top to receive a cigarette (5), and teeth (3A) round its lower edge (3) to provide an air flow for continues combustion when stood on a flat surface, and has an inner filter (6) to absorb smoke. The outer surface of the support is of a material that will take print. |
