If your boxes are closed and there is no internal indication, then they are probably fine. If you have the room, put all your singles in 5-finger bags on end so that the top is open and pointed upwards. Open helps keep the humidity exchange going. Check them every few days. Also, in 5-ers, you should be able to find room to do the freezer technique.

Make sure that you pulled everything from the cooler and cleaned the container.
