If the items don't sell, I will not be lowering the price as my daughter will use them. No splitting up the set. Note: For Rule 1, the first two pages of the first problem have faint marks from being written on and erased with an erasable pen. The rest of the book is unused. Rule 2 is completely unused. Both books have been stored at home, so please understand that there may be minor oversights and that they will be simply packaged. Please purchase if you understand this.
