Baby diapers are packaged in plastic bags and made of cotton. They can absorb urine instantly to prevent wetness from returning, and they have an excellent breathability function to keep the baby's skin dry. The baby diaper sizes available are: XL for babies over 13 kilograms; L for babies weighing 10-14 kilograms; M for babies weighing 6-10 kilograms, with 8 pieces per package; and S for babies weighing 3-6 kilograms.
