OCB Xpert Smoking Papers are extra thin to bring out the expert roller in you. The cardboard over and elastic closure protect the papers inside. Each paper is extra thin, lightweight, easy to roll and burns slowly. These high quality rolling papers are close to transparency and burn down evenly. Each single leaf is made of a watermarked pure flax paper for quality assurance and Arabic Natural Gum that has been extracted from East Africa which also makes it 100% Vegetarian Organic. A paper slip folded in with the leaves reminds you when you're running low.
