We have been buying tanks from Marchisio since the 1990’s, so we have a long history of collaboration.  Marchisio is a classic Italian tank manufacturer that represents the best value in the industry. Great quality at a very competitive price. All tanks have a classic marbled finish on the outside and a smooth polished finish on the inside.  Each tank includes a dry airlock – a style of airlock that has a marble inside to make a seal. We recommend replacing this airlock with a classic water airlock to reduce potential oxidation. Includes 3/4" chrome plated valve.
