"First let me tell you how well made these bricks are. The design is amazing and the time efforts of enjoying building with my 4 yrs old. i know it say 8 yrs old but my son loves lego and duplo . He got so excited for his lego superhero and he start playing with them as soon he woke up. Took me long to build because I was exhausted at the time. Overall recommend and follow the instructions. Thank you ,"
