I bought a 6-color ink cartridge pack because the gray cartridge ran out. However, the printer broke shortly after and couldn't be repaired, so I replaced the printer. The gray cartridge is already installed in the printer, so there are 5 colors remaining. The remaining 5 colors are unused, new, and genuine. I purchased them in September 2025 for 8080 yen. The price includes shipping. I hope someone can use them.
