I purchased the Mini Projects Set of 5, as well as the little Tool Set, for my 3 1/2 year old grandson. Its a Christmas gift so he hasn't seen it yet, however I've had a good look at it all myself. Fantastic presentation, everything packaged really clearly and safely, the quality of all the pieces is really good, nicely finished with no rough edges that he could hurt himself on. Great instructions included, everything you need inside each pack to make each project, and well sealed so it can't be opened at all until you intend to build it. Obviously these projects need proper adult supervision, however I can see how much fun and learning these projects will give my little "hands-on", creative grandson! I'm excited to watch him build his first project with help from one of us! I highly recommend these, and I would happily purchase more projects if more are added to the selection. 100% satisfied and delighted!
