This is a copy of the material, with the original writing erased with an eraser in an attempt to solve it again. I am selling it because I did not use it. It is a copy made by an amateur, so there may be some skewing, areas that are faint, and traces of the original writing. Problems only. ==================== ※ Instant purchase without comment is OK! ※ There may be changes between Rakuraku Mercari and Yuuyu Mercari shipping. ※ We will pack using recycled materials.
