This is a penlight purchased at Ado's Mona Lisa Yokogao (Side Profile) concert. (Maybe I have too many? But aren't they cute?! Penlights!) I only used it once at the Yokohama performance on October 13th. It lights up. Please be aware that it has been used once. It will be shipped with an insulation sheet inserted and in its original box. If you have any questions, please leave a comment.
