ecoEnvelopes makes envelopes easy to reuse-no more origami, no baffling instructions - simply zip open, insert your response and seal just like a normal envelope. Eliminating a reply envelope has the potential to take 80 billion reply envelopes out of the mail each year. Our window envelopes are perfect for statement mailings, direct mail, fundraising, surveys, subscriptions, membership renewals and more. They are available in standard and custom sizes in both business reply (BRE) and courtesy reply (CRE) versions. Our unique two-way patch envelopes are novelty solutions that make sending and returning envelopes quick and easy. They are ideal for consumers, small businesses and high-volume mailers. Recipients simply tear off the patch to find a preprinted return address or to add a new address to reuse the envelope. For high-volume mailers and custom orders, two-color printing on the back of the patch is possible, allowing mailers to add a coupon, customer survey or other promotional/remittance concept.
