On one side of the keychain, there is an 'ΙΣ ΧΣ ΝΙΚΑ' (Ἰησοῦς Χριστὸς νικᾷ) christogram that translates as "Jesus Christ Conquers". It is located in the four corners of the cross, which is a depiction of the 'ΙΣ ΧΣ ΝΙΚΑ' arrangement according to medieval Greek tradition.
On the other side, there is an inscription "Κύριε Ιησού Χριστέ, ελέησόν με" (Lord Jesus Christ, have mercy on me).
