With initials that stand for American Made Glass, this brand has stayed true to its name over the years. They manufacture all of their products from thick American borosilicate glass. AMG produces an expansive line of straight tubes and beaker bongs featuring artistic colored glass patterns. They also offer hand-blown bowls, stash jars and steamrollers for on-the-go and discreet smoking. For dabbers, they’ve created rigs with some of the most popular percolators.
