Secure envelopes

Sometimes you really need an envelope that's secure - no one can see what's inside. These are great. They are self-sealing, too, which is great. I'm a huge fan of these envelopes and highly recommend them.

This type of envelope is just so handy. It not only keeps things inside private but the closure is wonderful inasmuch as you do not have to lick-it to close it. Thanks, it's greyt.

Good quality privacy envelopes with self-seal strips

These are just basic #10 envelopes, but I'm happy with them. They have an inner printed design to provide privacy, and they have an adhesive seal so it's not necessary to lick the envelope. With 100 envelopes in the box, this should last us several years. The price is also similar to Officemax, although I didn't check Walmart. Having them show up in my mailbox is much better than driving to town and standing in line.

Strong and very private

I dislike absolutely nothing! These envelopes are great. The paper is strong, peeling adhesive better than licking glue and the black privacy is wonderful. I wish I had purchased these envelopes long before this. I will purchase them again when I run out. 100 envelopes will take a little time to run out for me. I am glad I will not have to buy any envelopes from anywhere else anymore. Like I said, wish I had bought them before!

how well they seal

Like: interior design-keeps contents from being viewed. Dislike: flap does not seal ALL THE WAY, i.e. at the far edges.

Blue Summit Supplies, Fast and Reliable!

Just what I needed! I've been moving slowly for the past few years, and my supply of self-seal #10's had slowly diminished, with the last few having lost their oomph. Now that my need to send out mailings from home has picked up again, these are exactly what I need and completely reliable. Thank you, Blue Summit Supplies!

Great quality security envelopes at a good price!

Great quality security envelopes at a good price. We use them with a laser printer, and they have held up nicely. (Other envelopes have had issues with the adhesive if I put them through the laser printer... but not these; they have worked flawlessly!)

These are every bit as good as name brands

Thought I'd try an envelope that was a little bit more economical (less expensive). These are every bit as good as name brands. Perfect for mailing checks. I always have to have the strip for sealing so this envelope was perfect!

These are good.

I was concerned about comments that these envelopes are "too thin". Nonsense. I just put a check in one and held it up to various lights, could not make out the contents, and besides, I use envelopes to pay bills, so there is always a statement of some sort with the check. Price is good, too.
