The HappyBear bamboo inserts are ideal for collecting stool in washable diapers. The inserts feel soft and comfortable on your baby's skin. Changing is quick and easy. You place a single unfolded insert in the washable diaper. Make sure that the insert does not protrude from the diaper to prevent leakage. After changing, simply throw the insert with the feces into the trash. There are one hundred inserts on one roll.
