This is an ARMY bomb that all ARMYs dream of. Well, ARMYs, the original name of all these devices is Light Stick, which each group has a special design, and this design belongs to BTS, and my name is ARMY Bomb. This device is like a flashlight. They shake them, which is very beautiful (I wanted to know it)
