The permanent adhesive makes sure that your labels stick and stay to a variety of surfaces without peeling, curling, or falling off. Avery barbell labels are carefully constructed with top features to provide the best results. Sure Feed technology reduces jams and smudges by creating a more reliable feed through your printer.
