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. of adhesiveAcid-freeSafe to use on photosPermanentNontoxic
