35 white plastic bottle caps, no markings Perfect for crafts like science projects! They have been cleaned thoroughly, but please refrain from purchasing if you are sensitive to used items, as they have been stored by an amateur. I am also selling 40 plastic bottle caps with markings. If you would like to purchase both sets together, I will offer them for 333 yen. Please let me know in the comments if you are interested. #ShippingIncluded #SummerVacation #ScienceProject
