AFM'S Flat Top banger with bell bottom bucket is a high quality, 100% quartz banger that won't break the bank. Utilizes 3MM thick quartz for optimum heat retention and durability. The 25MM XL bucket makes it easy to dab globs of material. We love AFM bangers because they look great, work even better and don't cost and arm and a leg when compared to American made quartz. The flat top banger is slightly harder to load but are easier to use with carb caps since the cap can rest on the flat top lid.
