TOMORROW X TOGETHER TXT OFFICIAL LIGHT STICK ver. 2 Tuba Penlight ver. 2 Moa-bong Batteries not included. I urgently purchased this official, new item here because a live concert was approaching this year. It lights up, but it seems to be a defective product, and I couldn't update or pair it no matter what. I gave up and bought a new one, so I will sell this one. I do not recommend using it at a concert. Please purchase only if you understand that it is a used item.
