Three sizes of nasal plugs (for optional use) included in each mask pack. Nasal plugs can be used to help reduce nasal breathing and dryness when using the Oracle mask. Many people find that the nasal plugs are not required, but most users do find them helpful for the first couple of weeks when starting to use the Oracle.
