Mama Colle Crystal Blue ★ Ballpoint Pen (Nakayoshi October 2006 Issue) This is a ballpoint pen my daughter used at the time. The frequency of use is unknown. The ink is in and it can write, but the amount of ink remaining is unknown. Please refrain from purchasing if you are sensitive to used items or if you are looking for a perfect product. This product has been stored for many years, so there may be scratches, scuffs, stains, discoloration, bends, etc. that I may have overlooked. Please understand this before purchasing. I think this is an item that is no longer available as it was at the time, so it might be good as a collection. Thank you to those who understand, fans, and those who like it.
