These scrapbooks are quite special. The papers in these books are made of a heavy duty recycled Ellie Pooh cardstock. You have to feel the paper to believe how nice it is. The papers are acid free and were designed for scrapping and preserving photos. A perfect gift for the elephant lover as well as the paper connoisseur. The pages in both books are thick enough to use both sides of each page. Additionally, there is a piece of tissue paper that protects between each page. Every book is individually handcrafted. High quality at a great price. An acid free crafters glue and vellum tape work best with these papers.
