I purchased this book for a little boy of 5, who, because of a physical disability, has limited use in his arms and hands. I have been waiting to hear from his mother to learn how he got on with it before writing this review. She told me the book was a good size for her son (A5)and the pages, being thicker than normal, are reasonably easy to turn. The dabber supplied with it was a good size for him to hold and does not run out of water too quickly, therefore he was kept amused for ages. He loved watching the different farm animals appear and the picture revealed was bright and cheerful. After about 10mins the picture disappears as it dries and is quickly ready to use again. She considers these books to be a good idea for children that have limited movement in their hands and/or arms as they feel a sense of achievement knowing they have made the picture appear themselves. There is no mention in the description of this book that it is reuseable and I think that should be added as it is a big bonus. As for me, I have more young children to buy presents for and I will certainly have this particular one on my shopping list again, and will be looking for more of the same!
