This is the new Diamond Glasss Moonrock ratchet perc to swiss perc straight stemless bong. It stands 16" tall and is just a stunning piece with all the added color and also a galaxy marble placed towards the top to really make it stand out above the rest. The function on this piece is just awesome. Two chambers of filtration, with it first going through the swiss perc and then up to the moonrock ratchet perc before heading to you for a smooth clean hit.
