Natural air-dried red pine firewood! Easy to ignite and with strong heat, how about it for pottery or kindling? We pack 10kg in a box. The length is about 40cm to 50cm, and the splitting is uneven. We appreciate your understanding. Shipping is included, and we will ship via Sagawa Express. We cannot ship to Okinawa, Hokkaido, or remote islands. We apologize for the inconvenience, but please be aware of this. Thank you for viewing.
