They protect the diaper while decreasing the need for rinsing. Comfortable and biodegradable, they are easy to use.
The liners have no absorption capacity; their only purpose is to prevent the fecal matter to stick to the diaper. They allow you to soak the diaper without having to rub it previously (rubbing should be avoided, as it will cause deterioration to the waterproof coating applied to the diaper's nylon layer).
Some customers wash the liners in order to re-use them if there was no stool in the diaper the first time.
Care: Simply toss away the liner in the toilet. It will simply disintegrate, as it is biodegradable.
