In the last 8 boxes that our company has purchased we have found that the inside seam on the window side of the envelope is glued at the seam. I have to use a letter opener to free the window side of the envelope in order for my checks to fit inside. This is a big hassel. Looking for another supplier.
I bought one box of these and returned it because there was too much glue on one of the inner seams. I had to physically separate the front side of the envelope from the back on every single one. The local store happily exchanged it for me but the replacement box is the same. I don't have the heart (or the time) to make another trip to the store so I'll just deal with it.
