Note: This package is empty to reduce shipping costs. You can choose a filler:   - Plastic beads (for BB guns) or rubber pellets.   - Throw sand (such as those used in aquariums)   - Beans (soybeans, mung beans, etc.)   - rice   - sand (usually the sand that washes the filter)   - pebbles (for intermediate iron) - BB or ball bearings (iron or steel - for advanced iron) The first two are recommended as fillers as they help to maintain the long life of the bag. Traditionally, the bag is filled with beans (soy or mung beans), rice and/or sand. If you live in a damp area, you must ensure that any organic material does not mold, so plastic beads are your best choice. Sand is the most common filler, and sanding (or washed sand) is best if it is available in your area.
