In 2002, this is a full set of 13 Hello Kitty bottle caps ("Monster" series) that came with Sakuma's candies: 12 normal types and 1 secret type. These have been kept at home as a collector's item, never displayed. They are in beautiful condition. Please understand that these items are over 20 years old and have been stored at home by a private individual. If you are concerned about minor details, please refrain from purchasing. I will respond promptly to any questions.
