I love these ease of these wood packs i just put them in my tiki fire pit and light the bag and all and i have a fire going i no longer have to mess with paper and kinlin wood to light my fire now thanks to these tiki wood packs.These bags last for a good 30 mins so this box of 4 would last ya 2 hours of burn time to enjoy some warmth gathered around the pit chatting it up with family and friends.I love that these packs do put out a low amount of smoke from them.
