Zip it up and leave it for 48 hours to absorb all the moisture. Then I carefully screw the front glass on whilst it is still inside the bag. It always works. The desiccant can be easily found on Ebay like this one..

To refresh it simply put it in the oven at 120C for about 2-3 hours and put it in the bag whilst still warm.
