This 7MM 16" MGM Big Beaker Water Bong is made with high quality Borosilicate Glass. It is a limited edition MGM Bong and is exclusively sold by Budder Bongs. The base of the beaker is thick and wider than your typical glass bong. It is great for a nice big pull to get you faded for the day. This MGM Bong is 16" inches tall and is 7MM thick in glass.
