As a reference, the classifications behind the numbers are as follows:
Uncured polymer does not need to be stored in an air-tight container as nothing is lost from the material while it lays dormant. It should be kept covered so it remains dust free and separated from other colors of polymer or even cured polymer as they will begin to bond together.
When storing canes and designs I haven't completed yet, I use plastic wrap as my cover of choice and then store the canes in a flat filing cabinet. Other designers wrap their canes and then store them on metal baking trays.
