Moomin Baby diapers are marked with the date of manufacture and production batch number on the production line for quality control purposes. This identification information can be found on each diaper as shown in the picture below. In addition, PANTS diapers are marked with the size of the diaper in brackets, e.g. in this picture (6) on diapers where the familiar large numerical size marking has been omitted from the front of the PANTS diaper.
