Corks and stoppers are designated by number depending on their dimensions. Cork is naturally occurring, while stoppers are synthetic. The proper one should be selected based on the dimensions of the opening to be sealed. The cork or stopper should not go too far down into the opening, or it may be hard to grasp.
