box that the letters come in is a low quality. The envelopes are heavey and when I picked up the box of envelopes the first time the box came apart and there were envelopes everywhere. It seems that if you are going to create a quality product you need to create a quality box that they can be stored in.
These envelopes with their tinted material are ideal for mailing items that should be hidden from sight such as checks or papers with personal data or identification numbers.
This business envelope is the perfect. How many can you say about an envelope? For me there are two necessities in an envelope. The first necessity is that the envelope should have an automatic self-sticking way of closing which this envelope has. It works very well - I think it has been improved through the years as before the adhesive that was on the envelope did not go to the end of the flap which would often require me to add a piece of Scotch tape to ensure that it was closed. The second thing is that you can't see what's inside. Two thumbs up!
