Disappearing Highlighter

Are you a college student who always has trouble reselling your textbooks at the end of the semester? Are you an educator, tired of children marking up your books you must use every year? If you said yes to either of these questions than you need to invest in the disappearing highlighter!! This is the answer to everyone's problems! The highlighter dissolves into the pages after 3 months. It doesn't smudge or run through other pages. When the semester is over your book will still look as good as new, allowing you to sell it for a great price. Your textbooks the student's used all year will still be in decent shape for the following year! This is the perfect tool for people of all ages and professions
