King Palm natural leaf rolls are individually handmade. All leaves are handpicked and cleaned with purified water before rolled. The leaves are very slow burning and resilient. It is best to keep them stored in a cool and dark environment. These leaves are from the flowering tree of the Cordia (Borage) Family grown on our farms across parts of Southeast Asia. Natural for this product means these leaves were not grown with toxic fertilizers and were not treated with harmful or artificial flavors. No harm to the environment is done, when leaves are cut from the tree, new leaves appear after a short period of time. Our production practices are sustainable, and the leaf, corn husk, and paper are all biodegradable.
