Fabric Conductive Tape with conductive glue is ideal for maker projects. The roll is 20mm wide and 30meters long. The tape is electrically conductive on the surface and the glue is also conductive so contacts can be made on the top or under that tape. Fabric conductive tape is flexible, does not tarnish so project continue to work for a long time.
Tip: Cut the silver tape not the white backing as it makes it easier to restart the tape.
