Kids Practice Copybook Set /disappearing ink pens

practice copybooks for kids. Bright multicolor covers to engage young learners. Includes workbooks for alphabet, numbers, drawing, and math. Designed for preschool skill practice and early learning.  Traceable engaging books with disappearing ink pens, so the books can be used over and over again. Great learning and shows math, the common core way which is taught at all schools now.   Some of these books have never been used. There’s one book called the fun drawing book that does have. Some scribbles on it that were not the invisible ink. Every other book is in great condition. There’s just one book that took a beating. I think 90% of them have not been used at all.
