Whether mountain biking, camping, or at a music festival, doob tubes allow you to keep a joint within reach at all times. These five-inch long pre-roll joint tubes protect your pre-rolls from the elements. Roll up a joint or two before leaving home and transport them in the EF420 doob tube so they don't get smashed. Pre-rolling your doobies lets you to light up in seconds, plus you can always keep a spare in your glove box or backpack for emergencies since it comes in a pack of two. Check out our selection of rolling papers while you're at it.
