I present you a new and very popular wooden toy, both for children and adults. Everyone loves it. Kids love it for the fact that they can hide something, their little secrets, and adults love them because many like the concept that is a book, but its something different. Unusual. Invisible before. This item is made entirely of wood and is completely handmade and hand carved by a skilled craftsmen. It is painted for a shiny, smooth and beautiful aspect and for long-lasting use. You can open it as you see in the pictures. You turn the part from the front of the book as you see in the picture, then from the same place you slide the top part. Then you can also rotate this part so you can easily hide something in the secret compartment. Please note: To be a real secret book, we have made the movable, moving parts a little tight. Thank you for your understanding. The external dimensions are 16.7 cm x 10.5 cm x 3 cm. The price is for one book.
