- Reviewed in the United States on August 15, 2024Color: Multi-colorVerified PurchaseI purchased a cheaper brand of block building and it was very frustrating. Lego sets are made of quality blocks, beautiful colors and easy instructions. The Lego sets are a bit more costly but they are well worth it. One box has three different things to build. It's a great activity instead of tablets, gaming or other digital devices. The end result is very satisfying.

5.0 out of 5 stars Perfeito!
Color: Multi-colorVerified PurchaseComo sempre, Lego com níveis de detalhe incrível. Peças de qualidade e ótimo acabamento.
Apesar de ser indicado para 8+ anos, montei para minha filha de 3.5 (com supervisão pois as peças são bem pequenas) e ela ama brincar com a casinha. Ela possui 4 cômodos e vários móveis/acessórios (além de ser possível montar 3 casas diferentes).
Ótimo brinquedo para estimular a imaginação e criatividade das crianças.
