This is a STAR LIGHT RING, a glowing white penlight for SEKAI NO OWARI's ARENA TOUR 2024. Operation and lighting have been confirmed, but it is recommended to replace the batteries before using it again at a concert. This STAR LIGHT RING has a belt that also glows, making the whole thing light up. I used it once at a live show and have kept it in its box ever since. Instant purchase available. ♯SEKAI NO OWARI ♯Sekaoa ♯Shinkai (Deep Sea) ♯STAR LIGHT RING - Brand: SEKAI NO OWARI - Model Name: STAR LIGHT RING - Tour Name: ARENA TOUR 2024 - Color: White - Features: Glowing penlight Thank you for viewing.
