Simply Self Seal Security Tinted #6 Business Envelopes, 3 5/8 x 6 1/2
These envelopes are great for sending checks or other small items through the mail. No one can see through the envelope to tell what is in them. I recommend to all these days!

I liked this in the past but it's now thinner and poor quality

Just what I wanted.
The security envelopes gives me a sense of privacy when I mail things in those envelopes.

We love Staples.
we have to travel 50 mins to get to Staples but find it worth the trip because they have everything we need. However we wish we could have our Staples back in Beaver County.
