I had to mail out about 350 letters for a group that I belong to. I couldn't decide whether to buy gummed envelopes or the self sealing ones. I had checked prices on-line and decided I'd buy the gummed envelopes because the self sealing envelopes were about $35 per box. When I got to the store I was looking at the different selections and there was an unadvertised special on the easy close envelopes at $25 per box. The envelopes were easy to stuff and made of good quality paper. I'm so glad I went with the self sealing envelopes because I can't imagine having to seal 350 gummed envelopes.
For the past two years I have been using the Staples Brand#10 Easy Close Security-Tint Envelopes. I use to buy them in 100 quantity. On my recent trip to Staples They had a 500 quantity on sale and saved my Company over $20.00. I use these to mail out invoices and to send checks. The Security works great. I love the ease of the peal off seal. Who wants to lick an envelope anymore and I hate those wet sponges gross. I just wish they would seal just a little bit better. I always feel better by putting a little extra tape on the outside for security. Over all great product.
These are really good nice thick paper stock easy to peel off tape security. I would use these for any documents like checks Social Security information DMV documents anything that you don't want anyone to know what is inside the envelope. Probably good for sending photos as well.
A Great buy for an association that sends out mailings every 3-4 months. Not only do they have the easy strip to peel & seal but they are light weight and don't add to postage.
