JO1 OFFICIAL LIGHT KEYRING This is a mini penlight-shaped keyring. It's mini, though. The size is different from the penlights used at live performances. However, it has been opened to check the operation and lit up once, but it is unused. Also, the insulator that was between the batteries had to be removed, so the battery compartment has been opened. The vinyl packaging has been disposed of. Official size: W40.5mm x H116mm x D40.5mm The light has 3 patterns: on, blinking, and fast blinking. The color cannot be changed. It will be packaged with bubble wrap and delivered in a cardboard box (Yu-Packet Plus). It will be shipped on weekdays as the procedure will be done at the post office counter.
