Each plug is very easy to fluff into an effective fire starting tinder that works in all seasons and all weather. Average burn times reported of up to 5 minutes for a single Fire Plug give you plenty of time to fuel your burning tinder. The commonly available cotton tabs fire starters on the market can get the job done if they don’t get too wet, the PROCAMPTEK Fire Plugs are like these cotton tabs on steroids.
