500 4X9 Letter envelopes
This is my 2nd or 3rd box of 500 4X9 business envelopes purchased from Staples. I still use snail mail and like the larger envelopes instead of the small ones that may get lost. I use envelopes for keeping some files too and tax paper receipts; you can fit a bunch in a large envelope. Works for me.

could not be worse!!
First the price on the shelf was (I believe ) $32 and then at the register it rang up as $26 and then I received this email quoting $21. The product leaves much to be desired.

Wish I had bought higher quality
I thought I was ordering on line the same envelopes as a dozen years ago. My use as a homeowner and family guy is general correspondence paying bills etc. These envelopes arrived as promised but they feel thin lack the slight sheen of the previous boxful. I think I would be embarrassed to use them for any typed/printed correspondence. I will probably drive them to m...

Delivery VERY Speedy
Both items arrived as described. Scotch tape seems to be getting flimsier in thickness. Tears more easily. Not the fault of Staples.

This Survey is Silly
These envelopes are size #10. They are white. One must moisten the adhesive in order to seal the envelope. These envelopes may be used to mail letter size letters.
