Your company can re-use boxes and cartons and still look professional! These full sheet Avery Shipping Labels are completely opaque, thanks to our TrueBlock Technology. They cover information that is underneath, including text, logos and torn courier labels. You can add your company logo and recipient details to the label using Avery software, and completely cover the existing information. You can save money on boxes, and still send a professional-looking package. This is a bulk pack of large sheets, which is great for regular shipping.
