About 500#9 Double Window SELF Seal Security Envelopes
76% praised the high-quality paper, but 24% found it too thin
I compared the paper quality of the envelope with my previous envelope. The side flaps of the current envelope are only about 3/8ths of an inch (more accurately 1 centimeter) whereas the non-selfsealing envelopes I had before were about 5/8ths of an inch (or about 1 1/2 centimeters).
Security printing is too faint and can be easily seen through the envelope, allowing the contents to be legibly read.
71% loved the crisp printing quality, while 29% experienced smudging

Security printing is too faint and can be seen through the envelope, but the black text of the paper contained within is legible enough.
The design of the envelope is a cost savings for us, but it can get frustrating when stuffing a lot of envelopes.
