These envelopes have two strong features: They are made of 24-lb paper instead of the 20-lb paper found in cheaper envelopes. In addition they are self-seal envelopes which eliminates the need to lick and seal (often in the dry climate in our part of New Mexico the adhesive on a regular envelope can dry too quickly after you've licked it so you may still have to use Scotch tape to help seal it). I only gave this product four stars because I think it is still a little over-priced for 100 envelopes; on the basis of quality alone I'd give them a five star rating.
needs more security can still see through if held to light. i put a used check in an envelope and held to light. i could see everything.if you want security check out another product!
I made phone request for shopping of 3 items by Staples staff with arrangement for pick-up by delivery service from Riverbed to Peconic Landing community in Greenport. Shopping was done efficiently and agreeably. All items were accurately identified and delivered.
