The double barrel bong from Grace Glass is truly a sight to behold. It is based on their classic beaker base designs but with a few new twists. First of all the glass has been changed from 4mm to 5mm, giving it extra strength and durability. The most exciting part of this new design is the brand new double barrel drum percolator! Blown with black glass it really stands out from the white creating a bold, hard hitting appearance. The percolator starts by taking the smoke upwards via the center tube and then splitting it two ways into the 'barrels' either side. The smoke is then taken downwards out 2 tight black drums, each with around 30 slits for a grand total of 60 smoke separations! After that the smoke and water hits the splash guard and ice catchers. Overall this is an incredibly attractive bong that will stand out from the rest for all the right reasons.
