The Double Double (PG1106) is considered by many as the most coveted piece by Pulse Glass. The first Double Double (Video shown below) was highly rated and known as one of the best flower pieces money can buy. The latest edition combines two awesome P.G. percs in one long tube. The bottom chamber contains their new double barrel stemline perc, plus the Fab Munny perc in the top chamber.
All in all, if you're a flower guy and you want to experience the best that Pulse Glass has to offer, then you cannot go wrong with this piece. From a function and artistic standpoint, you won't find anything else on the market it like it.
