30mm(diameter)×105mm(length) This is a dead stock key ring that was part of the MASERATI lineup of genuine accessories in the 1980s.
The black box with gold trident, when you think of MASERATI in the De Tomaso era, the BITURBO is probably the first thing that comes to mind. This item is reminiscent of that era.
The metal key ring has the MASERATI logo and the TIPO V5 racing machine of yesteryear embossed on the round ornament. A rare dead stock item from that era, a must have for collectors.
