I kept this gachapon item in storage, unused. It was supposed to light up when the button on the bottom was pressed, but it doesn't work anymore due to long-term storage. I assume the battery is dead. I think it would light up again if the battery was replaced, but I don't know what kind of battery it takes, so I haven't replaced it. If you purchase the Shiba Inu plushie I have listed separately, I will include this item at no extra cost.
