Something changed in the design
on January 30, 2025
Posted by: Nick F.
I mail a lot of bills per day. I was using the 1.27 oz. glue sticks (large) to seal the envelopes. Due to a change in design I've had to resort to the little Elmer glue sticks as the area to seal is thinner and it seems as if there is not enough "sticky" adhesive to seal the envelope properly even with a glue stick! CHANGE IT BACK!!

Okay product

The size is great but the quality is okay. The gummed part has very little stick and the paper weight of the envelopes are thinner than expected.

Need to also have the 100 pack as easily available in stores as the 500 box. I did not need that much!

Many of the sealants were already partially glued shut

First time I've had an issue with new envelopes but many of these are partially glued shut. The box looked fine so I don't know if it was in the manufacturing. I can work with it but it's annoying especially because they're SO expensive!
