I opened it, but I haven't used it at a live event or anything. It lights up in six colors. The bag doesn't close anymore, as shown in the third photo, because it's been open for a while. I will seal it with tape before shipping. ☆ I have confirmed that it lights up. ☆ Batteries will be removed before shipping. Please refrain from purchasing if you are concerned, as it has been stored by a private individual. Price negotiations are welcome. Immediate purchase is welcome. Item type: Penlight
