This bong tube from the 'Blaze Glass' Mix & Match (M&M) Series is made from 5mm thick borosilicate (Pyrex) glass & has an internal cooling spiral, a SG 45 standard grinding and comes with a silver ceramic transfer of the 'Blaze Glass' logo down the cylinder. The liquid in the spiral is frost-proof. Therefore, the tube can be pre-cooled in the freezer. This ensures an excellently cool and soft smoke.
