Thank you for viewing. This is the official light stick for IVE. It is an authentic product purchased from the official online store. I used it only once at a live concert, and no longer need it, so I am selling it. The included instruction manual is also included. The light stick itself has no scratches or stains, so it is in beautiful condition. Please consider purchasing it if you are a fan. There is some slight denting on the box. I will carefully package it and ship it quickly. Thank you very much.
