These flavoured King Palm leaves are empty tubes that allow for a very easy filling process with the included bamboo packing stick. These Cordia leaves are tobacco free and do not contain any preservatives, artificial flavours, or glue. The installed corn-husk filter is flexible and allows you to squeeze or bite them as hard as you want to create a flavourful, tighter and cooler draw when smoking. All King Palm Cordia Leaf Wrappers come with a one-year fresh guarantee, which allows you to store each all-natural leaf wrapper for quite a while.
