Simply place these reusable liners inside your baby's diaper to make diaper changing even easier! The liner will let all liquids through and retain anything solid (even solids that are more on the liquid side of things ;-). All you need to do after that is to add them to the laundry along with your dirty diapers (remeber to remove all solids before placing the liner in the wash).Features: -Included 10 sheets-Recommend having at least 20 liners for those who would like to use our reusable liners all of the time. Fabric: 100% polyester
