Set of 8 ballpoint pen refills in red, black, green, and blue. - Colors: Red, Black, Green, Blue - Quantity: 8 - Type: Frixion ballpoint pen refills I always buy the 4-color pen bodies, but I prefer the 0.38mm refills, so I replace them. Therefore, the 0.5mm refills that come with the pen are left over. There is no bag, but they are unused.
