Thank you for viewing. This is a set of 4 "Gakken Nande?" books. One book is brand new with the stickers still attached, but the others have stickers already applied. Please be aware of this. The drawing pages at the end of each book are untouched, so you can still use them. The contents are clean as they haven't been read much. There is a name written on the back, which I will erase with correction tape before shipping. Thank you.
