These are good-quality envelopes. The only problem is, the peel-n-seal strips stick to your fingers (static electricity), and sticky goop comes off as well. Secure as can be, but a pain to deal with. Switching to gummy seals instead.

I have been through a lot of envelopes over the last 20 years. I have experienced my share of envelopes that have the windows off just enough to cover some of my wording or the logo on my checks. These have the windows in exactly the right space and the self-seal is a huge bonus. No more glue sticks or licking! Fast and easy to use, good quality material, and priced right.

I've purchased a number of times and they were great. As for the box we just purchased, the address window is about an 1/8" higher, just enough to show the written $ amount of the check, which is unacceptable. We are going to have to trash them and buy something else.

Sometimes the windows can be a little off with other brands. These are the best I've found.

These envelopes fit my QB checks perfectly. Love the peel off adhesive strip, very strong and no licking necessary.

These are a perfect fit and work with the laser check in Quickbooks. FYI-these are a tight fit.

None of us want to be licking envelopes (or anything), these days. These envelopes are sturdy adhere well. They also have a dark gray/light black inside, which I love! Envelopes are always BLUE inside lol Black is a nice change up for me.....it's the little things:)

These checks are good but are for paychecks only. They fit my Quickbooks checks well. But you will not be able to fit an 8.5 x 11 letter or invoice in these. Only criticism is that you rip off the plastic strip and the adhesive seems a bit thick or has little chunks in some places. Not a big deal.
