Thank you for looking! This is a set of 3 English study books ✨ 1. Longman Active Study Dictionary 5th Edition 2. "Book to Simultaneously Acquire Grammar, Vocabulary, and Idioms Necessary for the TOEIC Test" by Taiji Sawa / Dai Nishida 3. MYBEST Clearly Understood English Grammar by Hirochika Hatori, Gakken These are the three items! As you can see in the photos, there are some markings with highlighters, though not many, and some pages have slight bends or folds, which is why I've categorized it as "slightly scratched or dirty." Since buying them new would be quite expensive, I recommend this set to those who don't mind minor imperfections or those who want to use them extensively for their studies!
