Consonant Edition No highlighter markings. Vowel Edition There is highlighter writing on only one page. It's on page 8, the "A, I, U, E, O Phonics Index" [see photo 11]. There is no writing or marking on the other pages. I stopped studying English before I got to the Consonant Edition, so I'm selling the two books as a set. Please refer to the photos for the condition. *In case I don't notice your purchase immediately, I've set the shipping time to 4-7 days, but I usually ship within 24 hours of my initial contact after your purchase. Thank you for your consideration. #English
