Thank you for viewing. I am selling this item because I accidentally purchased a duplicate. Please note that the three major benefits on the obi, including the practice mark sheet ①, are not included. This item is unused, but since the included practice mark sheet is not included, the condition is set to "Like New." Please refrain from purchasing if you are looking for a product in the same condition as new or if you are concerned about minor details, as this item has been handled by someone else.
