Thank you for looking! m(_ _)m This is a cheering penlight for Jang Keun-suk! (Includes a non-woven fabric drawstring bag) ← Some discoloration. I used it once at a live concert and then stored it. Lithium battery (CR2032, uses 2) The battery is dead, so I cannot confirm its operation. I apologize. The surface plastic sheet cover has not been removed. Please feel free to ask if you have any questions (*^^*) #JangKeunSuk #JANGKEUNSUK #JKS #Eels (fan club name) #KPOP Item/Type: Penlight
