I like these envelopes for sending out bills for our HOA. I include the from and to address on the invoice so I save time by not having to add this to the envelope. Also, I like the privacy design and the self-adhesive. The envelope is a little smaller than a standard size 10 envelope.

I am very pleased with these double window envelopes for our company checks. We use standard QuickBooks formatting for our checks--no special characters, no company logos. I measured our checks, our current window envelopes, matched them against at least 20 vendors' products on Amazon, even measured the envelopes and window placements on my computer screen. And I don't need or want to store 500 checks, which is the usual quantity. Regardless of all the research, being sight unseen there's always a bit of a risk the envelope won't be quite right for the check. So I was relieved when the order arrived and I placed a check inside one of the envelopes: perfect fit; payee and return address show nicely; no other information on the check is visible. They're even better than the previous envelopes we had used for several years. The self-sticking glue could be stronger, but it's as good as on other envelopes we've used. And the quality of the paper and security tint is good.

Boy do these save time. The fit was perfect for my group mailings. Good quality envelopes

These envelopes are just what I was looking for. The are perfect for sending out checks without having the lick each envelope. I will continue to order them.

Fits quickbooks checks, works for checks printed in quickbooks software but not for invoices or any 8.5 x 11 paper used for invoice printed on quickbooks.
