There are 12 types of molds for the Puni Puni Aquarium. These are molds for making and playing with friends in the field. Only one flower mold has a faint color remaining, which cannot be removed by wiping (photo 4). There is no problem with using it. *Please understand that these are used items. *Please be aware that these items have been stored at home. *I am a private seller, so there may be oversights.
