Redi-Seal Envelopes
The glue is dried and I have to either rub a glue stick over them to seal or tape them! I am not happy with these envelopes. I would return them but another employee has already added our mailing address to them.

Overall they're pretty good
Overall they're pretty good, but the glue isn't very strong. Maybe I just got a bad box, but it really doesn't hold. It's like it's dried out. Next time, I will spend the extra money for the reveal-and-seal.

QUALITY AND PRICE WORKS FOR US
The quality of these envelopes is steller for the application that we need. They are heavy duty with security and also, a self seal closure that actually works. Substance Solutions will definitely order again.

Secure envelopes
These envelopes certainly exceeded my expectations! Excellent quality and thickness and easy, strong adhesion of flap. All at a greatly reduced price! Another example of Staples done right!

Nice envelopes, but wish the glue was stronger
We use these for payroll checks and Invoices. The glue does not hold tightly and securely, making them easy to open. That is our only complaint. I DO like not having to seal every envelope myself. Being able to just lift the bottom flap and press the top flap down to seal the envelope is great! Major time saver!

Redi-Seal evelopes
They are middle of the road. We use them for our payroll checks and the glue does not adhere very well so we have to use scotch tape to secure the closure. Other then that they are suitable for our office needs

Redi-Seal Envelopes
These envelopes work fine, but I always tape them closed as well as the self-seal. When I have had to open them after sealing, they open pretty easily; therefore, the reason for taping. I would hate for them to open in the mail before the paperwork is delivered to the intended.
