Permanent glue tape is a double sided tape with permanent adhesive. Each roll of tape is housed in a container with a protective flap at the applicator to keep the glue clean. The adhesive is a special glue used for tape, so it doesn't dry. Perfect for scrap-booking and arts and crafts without worry of damaging your precious pictures.
