A simple but effective archival paper glue from Japan. Traditionally used for the fixing of washi paper to wooden frames in the making of Japanese shoji screens. Left dry the bond created should last indefinitely, but as damage and holing is an almost inevitable feature of paper screens, the glue will if wetted soften, release, and can be be wiped completely away allowing for clean repapering. Possibly a useful characteristic when used by children. 150g.
