From the Olive Young x Sanrio collaboration: a Hello Kitty (ハローキティ) keychain blind box where each design dresses Kitty in the food, costume or landmark of a different Korean region.

There are 12 designs in the series and every box ships at random — the design cannot be chosen, requested or exchanged. That is the point of the format, and it is what makes completing the set worth doing.

Each charm clips onto a bag, backpack, keyring or pencil case. Olive Young collaborations are sold only in Korea and tend to disappear quickly once a run ends, so these are hard to find outside the country.
