It’s nice when your bong has one percolator and even better when it has two! This sophisticated glass bong efficiently uses its interior space with double-filtering, venting and cooling water twice with tree-like air holes for extra comfort and suppleness. The 12-inch water bong is made of clear, heat-resistant high borosilicate glass with a clear pink hue on the bottom, top of the percolator, neck and mouthpiece. The curved neck of the water pipe adds visual appeal and makes it difficult for dirty water to reach your lips. Clean and hygienic.
