Sending out a direct mailing? Perhaps you are mailing company brochures, newsletters or other A4 marketing material. When you have a lot of mail to send you can prepare it in double quick time using the unique QuickPEEL feature. You simply divide the sheet along the perforation to expose the label edges and then peel and apply to your C4 envelopes. Avery EcoFriendly QuickPEEL Labels don't just save you time, they can help protect the environment too.
