I know there are a few of you out there who have/are using these as favors. What I am wondering is how good they taste after a while? How long do they stay fresh for? The last thing I want to do is give away stale cookies, and I just don't understand how they stay fresh long enough, unless they are wrapped air-tight or something.TIA :)I think these would be perfect-o for the favors at my bridal shower, which is why I'm asking
