From a quality point of view, this series of books is excellent with laminated pages and solid yet my son is far from a tender with its business. The quality is very good explanations, the designs are simple but well illustrate the text. For the specific case of "DIY", explains us the tools, what it must be in a tool box, this quest a workshop, a rack. It also talks about the DIY stores. Then explains how one paints, is lined, carpet laying, laying tile, made plumbing, electricity
It's very rewarding for children from 3 years and much more!
