Hello! We are former homeschool parents who spent 18+ years purchasing used homeschool curriculum for our family. We understand the importance of knowing what you are purchasing — and actually receiving a book or resource in the expected condition. So, we inspect books page by page, test media, and check over resources, doing our best to represent each item as transparently as possible. Your purchase includes: GOOD++ Exploring Creation with Physical Science TEXTBOOK (3rd Ed) — NO MARKS or WRITING. Interior of book like new. Front and back cover have been wrapped in tape to reinforce/cover. (See photos). Binding tight.
