Glue Strips are a required to use the SELCO book repair kit. Each strip will repair from 3-5 books, depending on the spine width/length. Glue strips are measured and cut with ordinary scissors to fit just short of the length of your spine. Don’t throw away those scraps, no matter how small they may seem! Scraps of your glue strips are saved and then used to repair smaller books, or can be combined to repair larger books. The $1.01 price per strip includes our shipping cost from Cover One.
