Air Mail and First Class
There’s no need to risk paying more money every time you need a supply of air mail envelopes. Our airmail envelopes feature the signature red and blue border design and they come preprinted with postal service air mail insignia (on the front and back) for fast identification while in route to any overseas destination. These number #10 size envelopes are lighter in weight than standard #10 envelopes to keep mailing costs down. While, they can be used for domestic mailings, to avoid running into United States Postal Service regulatory issues, it’s best to stick with international use.
Duo-Purpose and Multimedia
Make it easy for recipients of your marketing message to send back a timely response via the mail with our duo-purpose mailers. Designed to encourage a faster response, once the recipient reads your marketing materials, they can use the same envelope to send back whatever response you desire. This removes the extra steps of finding an envelope and stamp, which can cause a delayed response or the dreaded no response due to loss of interest.
Heavy Duty and No-Bend
Heavy content such as booklets and catalogs can cause regular mailers to tear or rip during processing or transit, and that’s not how you want recipients to receive your materials. Avoid this risk by choosing any of our heavy-duty mailers made of strong, durable paper. Preserve photos and artwork with the protection of a no-bend mailer.

Don’t forget we also offer custom labels, custom envelopes, custom filing folders as well as custom business forms.
