On Quickbook checks the checks are tight in the envelopes so when slipping the checks into the envelopes they get caught on the back of the envelope. They have a square cut back with "tabs" on each side instead of the usual "V" type cut on the back. I won't purchase these again.
Envelopes would be fine but they do not stick when moistened. You have to get a glue stick to seal every one of them. Staples envelopes keep getting worse instead of better.
I ordered these for our company checks. They were supposed to be the "same size" as our last envelopes. All the measurements matched. However these envelopes are a bit more snug. It take a little longer to get the checks pushed in where as my last check envelopes the checks just slid in. May or may not buy again.
The envelopes are a good quality and weight and they fit printed checks. But the memo line on standard printed QuickBooks checks is visible through the window. Had to return and purchase envelopes elsewhere.
