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.

Only envelopes I use.
The only envelopes I will use. These envelopes are so easy to use with the convenient self adhesive. I like that when I write on them it is clear and does not smudge. They are great for privacy also.

Good Envelopes
They are pretty good but after a year or so they lose their stickyness.
