I go through a lot of envelopes and these ones I think are the best. Well the box I got was anyways, only used 500 so far. Why I say they are the best because almost every envelope will taper slightly at the bottom corners. Getting envelopes that are perfect 90 degrees on every corner is like non existent. It usually is only an ever so slight taper and will process through machines that require #10 envelopes but it is noticeable if you line them against a straight edge and this ones were fantastic.

These envelopes could be a little thicker. They are worth the price and will work for what I needed to mail.
