Sekine Masao's "The World's Easiest TOEIC Test English Grammar" The book itself is in good condition, but there are markings with a highlighter and ballpoint pen on about 40 pages (about 1/10th of the book), as shown in the second image. As far as I have checked, there are no writings in the text, so please consider purchasing if you don't mind. I want to sell it, so I will also consider lowering the price (❀ᴗ͈ˬᴗ͈)
