This is a set of books: a guide for adults on interviews and application forms, and a practice book for children's interviews. The children's book has never been used and hasn't been opened. The adult book has been read several times. There is a fold mark on the upper right corner of page 79 (see photo 9). This is the only fold. I tried to handle it carefully, but there is a general feeling of use. I look forward to your purchase if you understand that this is a used item.
