Fresh fan leafs are second best to use. The best thing is found in tobacco stores and used by pipe smokers to keep their tobacco moist. It's a small metal disk with holes in it. You soak it in water for about an hour and it lasts around 5 day's.

You do not soak the fan leaf just warp the bud you want to add a little moisture to and in about 12 hours or so the dried bud is revived again

Apple peals do not have much moisture in them and they will collect the small swag left in the botton of the bag. Then what are you doing to do, smoke the apple? lol Just use a fan leaf, it's what you are looking for.

Peace
