Staples #10 Self-Seal Business Envelopes

Absolutely horrible. I have to tape each & every envelope to be sure it stays closed. Sadly, I purchased 3 boxes! Never purchase those again.

These envelopes actually seal, and actually provide good tinted security
I would recommend this to a friend!

These envelopes do not seal securely at all. They are easily peeled open enabling tampering.

I volunteer at several local non-profits. For mailings from 20 - 200 these envelopes speed up the process of stuffing and sealing. Once sealed it stays sealed. I can buy cheaper envelopes but efficiency and speed is lost. These are worth the extra cost.
