What exactly are Amico Sweet Palm Tubes? Amico Sweet Palm Tubes are the world's 1st & Only 100% tobacco-free natural leaf tubes for smoking or enjoying your favorite herbal incense's aroma. The exotic leaf that these naturally sweet and tasty tubes are rolled from is a closely guarded trade secret. They come from a remote region in Thailand not many people have access to. The leaf is moistened and rolled into a hollow tube. At the end of the tube which is cover by the leaf, there is a porous woody substance (actually a small plug of corn husk) which serves as a filter. At the opposite end of the tube the leaf is cut at an angle so as to allow the user to easily drop their favorite smoking blends into the hollow end and then stuff with the wooden poking stick that is provided in every pack. No rolling skill is required. Just stuff & smoke. Amico Sweet Palm Tubes burn slowly and evenly and have burning characteristics much like a premium cigar. The green leaf has veins running through it which add to its exotic charm.
