I REALLY LIKE THE SECURITY TINT SO NO ONE CAN SEE WHATS IN THE ENVELOPE. I LIKE EVEN MORE THE QUICKSTRIP SEAL. JUST PULL OFF AND CLOSE. NO LICKING. I'VE HEARD THAT THE ADHESIVE IS BAD FOR YOU.
The strips that cover the "glue" on the flap of the envelopes are NOT properly positioned. Some envelopes are already half glued shut when you try to use them. The strips look as if a person in need of eyeglasses placed them. I will never buy these again.
