Ad brochure is interesting and useful

I have studied a brochure about olive oil lately. It is a free brochure displayed by the olive bottles on the shelf for customers to take and read, in which certain olive oil is introduced along with a few related recipes. From the brochure, I have learned not only a kind of oil but also new words that I didn't know before. Besides, I can learn about the sentence structures, therefore improve English writing skills. Ad brochure is interesting and helpful to me.
