    After managing several charity campaigns and manually sorting envelopes for each cause, I was extremely fatigued. Prior to my next campaign, I discovered, which offers colored return envelopes. By assigning a different color to each account, I could instantly identify the corresponding cause for each envelope. Thanks to Business Envelopes, this process has become significantly easier!

    I'm glad I found these. I still mail checks in to pay bills, so I needed a smaller envelope for them. I always hated having this tiny check in the big 10" envelopes. I also appreciate the added security mesh. It makes it hard, if not impossible to put the envelope against light and read what's inside. These are super quality too, and don't feel like cheap, thin paper.

    It's hard to imagine that something as simple as envelopes can exceed one's expectations, but these envelopes did. I loved the bright yellow color, and the size just as I wanted. Plus, the quality was perfect.

    I bought these to put important correspondence in them. People would say I never saw it, because it mixed in with their regular correspondence or I missed placed it when I set it down on my desk. Nope no more. Not one person has told me they missed placed it or didn't get it. I will be buying more of the neon colors. They are perfect!
