Ketsumeishi POWER UP Mushroom ※This is a penlight. I've forgotten which concert I bought this at, but it's a penlight that I only used once at that concert. After the concert, I stored it in a dark place. There may be scratches from use at the concert. I've replaced the batteries with new ones, and I've confirmed that the light turns on. This is a used item, so please refrain from purchasing if you are looking for a perfect item or are very particular about condition. Please purchase if you understand that this is a used item. The transparent case inside is slightly deformed as shown in the photos.
