I absolutely love these envelopes. There is not much worse tasting than envelope glue. And when you're mailing a lot of envelopes you might as well forget about supper. You won't need it. These envelopes are so easy to use. Just zip the strip of paper off and fold to close. It's fast neat and doesn't taste yukky. Not only that but they are security envelopes which means things you want mailed won't be "spyed on" by others. I would not hesitate to recommened these evelopes to anybody!
