100 gsm of dry kozo pulp for use with Awagami's "Kami-no-moto' papermaking kit (sold online here) or for other papermaking setups. There's enough dried pulp in each set to make approx. 50 postcards. Pulp can also be soaked and used for paper relief or for sculptural artworks. To use, soak in lukewarm water for 10 minutes and then pull apart to disperse the fibers.
