This is the official ZEROBASEONE (ZB1) light stick. I used it twice at concerts. I have confirmed that it works and lights up without any problems. There are no noticeable scratches or stains, but please refrain from purchasing if you are concerned about minor details as it is a used item. When shipping, I will remove the batteries, wrap it in bubble wrap, and pack it carefully in a cardboard box. Instant purchase is OK ⭕️ If you have any questions, please feel free to comment.
