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.
I needed to use these for a mass mailing I was doing for my women's group and they worked perfectly! They were thick enough so you could not see through them to see the contents and they were strong enough to hold up under the whole mailing process. I did have several pieces of paper that were going to be included plus several of different sizes and this envelope worked perfectly. I also must admit that I liked the fact that I could just take off the stripe of paper and stick the envelope securely closed and did not have to lick all of those envelopes!!
