These envelopes are good but the glue on the flap closure is bad in the middle it was caked on pretty thick and in other areas none at all I had to tape these envelopes to make sure they were sealed shut.
Good for personal use as well as for business. I may even use some envelopes for fun activities for children. These envelopes have real "stuff it" appeal.
I used these envelopes for a special calendar that I needed to mail but used them as well when personally giving the calendar as it looks nicer than a manila envelope and much easier than gift wrapping.
