Almost clean, but some have minor black lines. These were used to hold the product in place, so please understand that these are used items before purchasing. (They still function perfectly and stretch well.) There are 51 rubber bands included, though the listing is for 50. *If you wish, you can add more for 20 yen each. #RubberBands #RubberBand #O-Band #Crafts #ArtsAndCrafts #Art #Stationery #OfficeSupplies #ElementarySchool #Kindergarten #NurserySchool
