Kiribako are boxes made of paulownia wood. Paulownia has humidity-controlling and insect-repelling properties that keep rice fresh and protect its flavor. This box is also suitable for storing brown rice, wheat, beans, millet, cereals, and other grains. Available in three sizes, boxes of different sizes may also be stacked together – the height of a 1 kg(2.2 lb) box and a 3 kg(6.6 lb) box stacked together is equivalent to the height of a 5 kg(11 lb) box.
