From the Manufacturer:
This starch paste is a must have for all paper projects. From bookbinding to scrap booking, from archival to collage, it dries slowly for intricate readjustments and it is safe to use even with the most delicate papers. Works wonderfully for Bunka embroidery. Dries clear and incredibly strong yet it is entirely reversible in water. Will not wrinkle or soak through paper or fabric. Non-toxic, acid free and washes off hands and out of clothing easily. Adheres to paper, glass, metal, plastic, wood and fabric. Nori Paste can be mixed with PVA glue.
