I do love these envelopes and we are a small business, but I got the ones with the plastic that comes off so it adds a little extra time when doing bigger mailings, not a big deal though.

fit 1 check and 1 time sheet snugly. no more than that.

I like the overall quality of these envelopes. Windows are correctly placed for checks; paper weight of the envelope is better than the last brand I bought from an office supple company. The only complaint I have,which for some companies would be very NOT good, the right hand bottom seam seal was stuck in every envelope, so far first 50 - maybe bad lot of sealing sides. It will pop open if you manually push open the inner bottom corner. Then the addresses appear properly and good to mail.They are a hair larger than the 9 size- making it slightly easier to stuff, if it wasn't for the corner issue. I'm guessing they are not all like this. I'd give this product a 4 rating.

Appear to be good quality for price. Like the ease of self sealing.
