With respect to how to store the beads, the simple answer is watertight. This can be a simple plastic bag with a special knot, a sealed bag, a laminated pouch, a plastic box (but not all plastic boxes are watertight), a glass jar or a metal drum, or even combinations thereof.
The intended storage time is also relevant, as most plastics leak air and moisture through the material at some rate. It also is in relation to the temperature of the storage and the quality of the lid or closure.
