Price reduced: 820 yen → 680 yen → 520 yen This is a novelty item of Mitsubishi Pencil mechanical pencil lead refills. It's likely from the 1990s. The price is for all four items in the first photo. These are items remaining in the store. They are unused, but show signs of deterioration. There is also staining on the erasers. They can be disassembled like a puzzle. I don't recommend using them as erasers because they are old. They are probably for eraser collectors. They will be shipped via Yu-packet Post. Please note that the box may be damaged during shipping.
