Easily update old information and create stickers, qr code labels, packaging labels, and more with Avery TrueBlock 3/4" x 3/4" Matte White Square Labels. Easily revise old labels with Avery TrueBlock technology. The proprietary TrueBlock feature completely covers up markings and printing so that none of your old data shows through. This also provides better contrast for your new print to stand out on a completely white background. The permanent adhesive makes sure that your labels stick and stay to a variety of surfaces without peeling, curling, or falling off. Avery square 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. The print-to-the-edge layout lets you print beautiful full-bleed designs that fill each blank sticker to the edge. The patented Easy Peel label design makes these labels easy to peel and quick to apply. Just bend the label sheet, peel off your labels and fold the sheet back flat. Easily customize pricing labels, product labels, and more with your own art, symbols, and messaging by using the templates and designs on the Avery website.
