I was going to order check envelopes for our company, $750.00 for 5000 envelopes with our logo them. I figured it was worth giving these a try. The envelopes work great. The payee is clearly shown through the window and the logo on our checks shows clearly. I figure most people/companies receiving the check are more concerned with what's in the envelope versus a fancy logo on the outside. You can't put a lot in these envelopes, a check and maybe a stub. Great buy.

The product is of good quality, but unfortunately does not fit more than a check. I needed to send invoices so they are at no use for me.

We've used these envelopes for years at our company (not always ordering through Amazon though) and this was a great price and with Amazon prime delivery, we got them lickety split.

These are smaller than other #9 envelopes. They not 3 5/8 x 8 5/8 as advertised but are3 11/16 x 8 9/16. Even a perfectly folded 11-inch paper will not quite fit top to bottom with two folds. With the increased thickness of 4 layers of paper, putting the paper into the envelope takes considerably more time as the envelope is only 1/16 inch wider than standard US 8 1/2 x 11 inch paper. If you are sending two pieces of paper it really does not fit. If you have several to send, a significant amount of time will be wasted compared to using a real #9 envelope. #9 envelopes, which are the smallest practical size for this purpose, are 3 7/8 x 8 7/8.

This is an exact match to another envelope we were purchasing for much more. These work well and are much more cost effective. Have ordered these a couple of times now, all good quality.

Just started using these today and the adhesive does not seal the envelopes - need to use a gluestick to do so

The width of the envelope is 8 9/16", not 8 5/8". This makes it difficult to insert our 2-part checks. In addition, the return address window is 2 3/16" from the bottom of the envelope, not 2 1/4". The window itself is 13/16" high, not 7/8". This means the top of the return address window is 5/8" from the top, rather than 1/2", which cuts off our return address. The photo shows the new envelope on top, with an old envelope from the same manufacturer on the bottom.
