Does not work well with the printer so you waste more than you print. The flap does not stay folded right so the return address ends up half on the flap and half on the front and everything is crooked and a mess! Out of a box of 50 I wasted at least 20. If you are hand writing everything these envelopes work well for odd sized items.
I used it to give out baby shower invitations. I liked it because it didn't have that regular envelop look. It brought a little more class to the invitations.
These did not work with my Intuit/Quickbooks checks. I returned them to the store and had no trouble at all with the return. I tried all the business envelops they offered in the store and had no luck finding one to work with my checks.
