Thank you for viewing. This is a book from the MINX Cut Academy. My child used it at vocational school. There are no markings inside, but there are signs of use where the book has been opened. There was a name written on the back of the obi (sleeve), so I erased it. As a result, there is some color transfer where the name was and where it overlaps with the main body of the book. Please understand that this is a used item before purchasing.
