Business-sized envelopes that are hassle-free!
I like these envelopes because they have a "tape on the flap that peels easily and sticks easily, which allows the envelope to close securely.

These are the ideal envelopes for many uses. I use them not only for mailing letters, but also keeping track of receipts and important small papers. They are great!

Problem with EasyClose Self Seal Strip
The Sealing Strip on envelops is not fully coming off, gets teared after 1.5inch on both sides, which requires us to use glue over the whole sealing area to actually close the envelop.
We had these in the past, and this is the first time we experienced this issue.
Other than the seal, the actual envelops are fine.
