We don't use anything but EasyClose Security-Tint Envelopes. Love the secure privacy quality and self-sticking flap. Won't use any other kind in mail. Staples always has best price.
Love these envelopes!! I run them through my ink jet printer to put return and addresses on them. The easy pull seal make's it easy to seal especially when you have to seal 100 letters. The pull seal is easy no more yucky licking the seal not only disgusting but also gross tasting. I highly recommend this product!!
I purchase these for the church office. Each week I mail bulletins to shut ins moved away parishioners snow birds etc. These envelopes make it so much easier and faster. I use preprinted labels zip-strip envelopes as I call them and in no time 20 envelopes are in the mailbox. They have a secure seal not those stick here and not there strips. If I am mailing 200 letters I have a basket near by because the strips become a wild mess on the counter and seem to have static electricity.
I have a monthly mailing that I send out. Stuffing all of those envelopes and then actually closing them addressing them and stamping them is a lot of work. These envelopes make that much easier and less time-consuming. They cover the document well. The peel and stick portion peels off very easily. They have a pretty solid didn't want to lay them down.
