Columbian #10 Double-Window Self-Seal Security Envelopes, For Business Statements, Invoices, 4-1/8" x 9-1/2", White, 24-lb, 500 Per Box (COLO134)

the stickiness was excellent. no problems

These envelopes work so well for mass mailing! Quality in design makes them so dependable, no folds or stickiness.

This is my fourth box of these and they are great envelopes.

Box was delivered during a rain/snow storm, but in a plastic envelope, so I'm not sure if this could have negatively affected the self-stick sealing of these envelopes, but they were very dry, didn't appear to be damaged in any way. They did seal, but with just a finger, you could easily re-open the envelope. The box had a '2022' date, so I don't think they were too old... but anyway, the security paper is fine and the quality of the envelopes otherwise appeared to ge good.

Perfect. Worth the price

the glue on the envelope is dry and does not seal the envelope. very thin, I do not recommend

Technically these envelopes fit QuickBooks checks as the description states but they are TOO BIG so you can see amounts of checks written, etc. that shouldn't be showing. Just a heads up! Other than that, they are fine envelopes.

Solid envelopes. The adhesive quality is up to par with any leading brand of envelopes.. I would definitely purchase again.

Excellent envelopes for the price

Great envelope. Double window eliminated work

Good quality and great price 10 out or 10

No good, charge credit card without any notice.
