3-1/3 in x 4 in White Printable Shipping Labels - 600 Pack

Our review of these 3-1/3 in x 4 in white printable shipping labels finds them best suited for small businesses and home shippers who need consistent, jam-free results and the ability to hide previous markings. The biggest reason to buy is the combination of TrueBlock technology that completely covers old labels and Avery's proprietary Sure Feed system that reduces printer jams, so batches of labels print cleanly every time. For anyone who prints address labels, returns, or product labels from a laser printer, these sheets offer reliable adhesion and straightforward customization.

Key Features

• TrueBlock technology: Completely covers old shipping labels and markings so reusing boxes looks professional and keeps tracking barcodes readable.
• Sure Feed design: Proprietary sheet edges and feed accuracy reduce jams and misfeeds for consistent laser printer performance.
• Customizable templates: Free templates and mail merge tools on Avery's website make it easy to add addresses and graphics without complex software.
• Strong permanent adhesive: Labels stick securely to most smooth surfaces such as cardboard, plastic, glass and metal for dependable mailing and storage.
• Bright white finish: High-contrast printing yields crisp addresses and barcodes for professional-looking mail and packages.

Who It's For

These labels suit Etsy sellers, small e-commerce businesses, and anyone who ships regularly from home and needs a practical, printer-friendly solution. The pack size and TrueBlock feature make them especially useful for sellers who reuse boxes or need to conceal previous shipping information without replacing packaging entirely.

Those who primarily use inkjet printers or need unusual shapes should look elsewhere; these sheets are optimized for laser and heat-based printers. If you require waterproof or removable labels, a different adhesive or material would be a better match.
