It looks like the crates of TNT from Kentucky’s Black Rock Powder Company will blow your place sky high but the fact is, they’re not explosives, just fire starters. Made from recycled sawdust & paraffin, these 8-inch long dynamite-style fire starter sticks come packed in a cedar wood crate & burn for 30 minutes. Comes with one wooden 'dynamite' box and twenty fire starter sticks. The original box is approx 16" x 10" x 7" and it weighs 12.5lbs.
