The Small PECS Communication Book is a 7 1/4" x 6 1/4", 6-ring binder made of a thick poly plastic material that is smooth to the touch, yet extremely durable. The book includes two Small (non-tabbed) Insert Pages, one Small Sentence Strip, and strips of hook (rough) VELCRO Brand for self assembly so you can customize your book. The back of the book is longer than the front to accommodate the Sentence Strip. This allows access to the Sentence Strip no matter which page in the book is in use. Insert pages and sentence strip may vary in color. Pictures sold separately.
