This Pulsar fat bottom banger is made of high quality quartz.  It's a 90 degree banger nail with a colored thick bottom for optimal heat retention.  It features a frosted Pulsar logo and a groundless joint for a more solid connection.  The inside diameter of the bucket is 14 mm. 

This banger is made of premium, 100% quartz that's 5mm thick.  This means it holds heat longer than cheaper variants of quartz.  The added color makes this banger nail more fun to use and look at.
