I was a little disappointing in that these envelopes weren't as nice as other brands I've used in the past. They feel a little flimsier in your hand than the average #10 envelope.
It is often OK to have value orientation AND expect some degree of quality for that value - otherwise... Security envelopes are either correctly folded sealed glued and printed or they are not. Staples brand envelopes often have a few with variations of the above problems but not enough to warrant major complaints - "value" being considered.
