These are perfect for toddlers and easy to build with, Nellie is very independent and loved stacking these together and making different objects. Nellie loves anything that moves so was very happy with making the car. They are the perfect toy to keep them entertained for hours. We also used this as a little bit of a learning game with colours. These are brilliant value for money and can be found on Amazon. These amazing two sets also come with a travel bag for all the pieces so you can take this toy on the go with you, perfect to keep little ones busy when out and about. Would definitely recommend to anyone who has a little one that loves building.
