Envelope
The envelopes serve their purpose well. I like not having to lick the envelope to seal it

Most helpful critical review
Posted Jan 5, 2018
Worst ones I have ever used.
They do not stay closed. They will open within 5 minutes of sealing them. This is not acceptable for a company sending confidential information. I cannot recommend these. As the other reviewer stated, buy lots of tape too.

Do NOT Recommend
These envelopes do not seal all of the flap of the envelope. This doesn't allow them to be ran through a postage machine. Would not buy again.

Not great quality
The envelopes are flimsy and the adhesive strip sometimes tears when you remove it and the edges do not stick very well.

Great Price
That's a LOT of envelopes for a great price! These envelopes provide security with an inside pattern and the peel and stick closure is a must have! Great deal!!

Changed and made cheaper
I've been buying this no.10 Staples envelope for over 10 years. Always loved them, now they've changed the quality. Much thinner and the sticky pull tab is half it's previous size and not very sticky. Now I have to use scotch tape to make sure it stays shut. Very disappointed, will not order another box, think I'm going to throw them away, they're useless.

not worth it
the glue on these envelopes do not adhere. Many of the envelopes, 2-3 out of every 10 have issues with the sides not being secure, and I tape over the top seal on nearly every envelope I use. One would expect a self-sealing envelope to actually seal. I won't buy this brand again.

Price is good but product is cheap
The price of this item is great. However, the product itself is cheap. The envelopes are very thin and the strip that seals them is quite narrow. They will work but I probably wont use them again
