Dryads are tree nymphs in Greek mythology, which makes this book particularly great for those interested in nature or fairy studies. The size is 10 x 12 and made from Birch Wood. There is no metal on the book. The leather straping on the book is actual leather and not imitation. Leather is left long so it can be used as bookmarks for the book. 30 sheets of paper included. This book will hold up to 500 pages. Allow 3-4 weeks for delivery as this is handcrafted.
