I am selling this item to organize my collection. Since it is unopened, the specifications are unknown. Is it a fluorescent marker? An eraser? I'm not sure. Please understand. Although it is an unopened, unused item, the packaging has scratches and wrinkles due to long-term storage. It is also unknown whether it can be used. I believe this is a very rare item as it is a limited edition overseas. It will be shipped via Yu-Packet Mini.
