This very thin and transparent pressure sensitive archival mending tissue is non-yellowing, removable with solvents and has a neutral pH. To use, dispense a length of tissue, place over the tear and burnish with a bone folder. Working the adhesive into the tear causes the adhesive to strengthen the tear as well as cover and support the area around the tear. A much better choice than common pressure sensitive clear plastic tapes that can yellow. A must for those charged with preserving vital records. 

Comes in 2 roll sizes 50' and 12'
