my overall experience with Staples products is very good. However the quality of these self-sealing envelopes is lacking. There is a flimsiness to the envelope and the inserted paper catches sometimes on the plastice window. There were too many spoiled envelopes due to the machines flipping part of the adhesive flap rendering the envelope unusable. I had to do my own quality assurance looking at each enevelope within a box of 500. I called the number on the packing slip and spoke to the representative advising about my issues. The rep was courteous and I encouraged them to have the machinery cleaned and adjusted. I also advised that the entire batch of envelopes needed quality assurance. In kindness to me I received a $10 gift certificate to use the next time I shopped at Staples. Service was very good at the call center.
These envelopes do the job fairly efficiently. It is nice to have the blue shading to prevent others from being able to figure out what is inside the envelope. Having one half of the sticky side folded over took a little getting used to. I also observed that occasionally the glue did not seem to work or activate properly. On several occasions I had to supplement using scotch tape in order to get the envelope to stick properly. Overall it is a decent product at a reasonable price. I would buy this product again -- when it is on sale
I've used this product exclusively for 4 years. I've seen a steady decline in the quality over the last 18 months. These issues have been relatively minor but each box seemed to have its own problem. Today I open a box of 500 and 60 of them are already sealed tight. This used to be a quality product.
