Bought this for our 3 1/2 year old grandson, who loves to help Dad and Poppa build things, and is very "hands on". What a delight! Everything is the perfect size and weight for little hands. Definitely needs to be used with full supervision from an adult, as these are "real tools", not toys. Very impressed, everything came beautifully packaged, and the tools are very good quality - great value! Highly recommend this for a young child who is going to be properly supervised. We also purchased some of the little starter kits.
