Comes with two regular Liner Inserts and two Wing Liner Inserts (regular cotton colors will vary). Liner Inserts enhance the absorbency of Pads to meet your particular needs, and will last approximately as long per use as a comparably-sized disposable pad or tampon. A single Pad will last you through a full day of your cycle, provided that the Liner Insert is changed before soaking through. Unlike Pantyliners, Liner Inserts must be used in conjunction with a Pad. 

How many Liners do I need?
You can expect to use 1 Pad per day, changing your Liner Inserts 1 - 6 times, depending on how light or heavy your periods are. When your Liner Insert becomes saturated, replace with a fresh, dry Liner. Multiple Liners may be added (up to 4 at a time for very heavy flows) to help prevent leaks or extend the time between Liner changes..
