This is a good luck item for students taking exams. It's an octopus (which is said to mean "you will pass" - "oku" meaning "to place" and "ukaru" meaning "to pass"). It comes with a ball chain and can be used as a keychain. I received it from an acquaintance and have kept it without ever using it, so I'm putting it up for sale. Please understand that this is a used item.
