Hayaku is a Japanese Mulberry Paper coated with acid-free water activated adhesive. This extremely strong, long fibered hinging material saves both time and money. It is used for hinging work of art on paper, repair of paper and structural applications in art, bookbinding, memorabilia and conservation. The adhesive dries strong and won't creep. Easily reversible with water. Please note: To remove, apply enough water to saturate the tape. Wait (patiently) for the water to penetrate the paper and adhesive. Remove and clean up adhesive residue with water.
