This glue runner is compact and simple to use, with a unique roller applicator that is flexible and easy to maneuver around corners and curved areas. It provides a precise, no-mess way to apply double-sided adhesive, and unlike liquid glue or glue sticks, there's no drying time and no wrinkling. The plastic applicator fits securely in the palm of your hand and opens on a hinge to allow for refill cassettes.Details:8.75 yd. runner length12 runnersAcid freeSafe to use on photosPermanentNontoxic
