Also known as "OCB Blacks", the Premium line of OCB rolling papers dates back to 1999. The sheets are thin, chlorine-free, and designed with lateral watermarking to provide a gradual burn. These papers are made from flax plant fibers and are so thin that you can practically see through them. OCB Premium papers burn evenly and leave minimal ash. 100 Sheets per pack 1 1/4 Size Made using Natural Flax Plant Fibers 100% Natural Gum Arabic
