Review: My kid love these blocks. Never new that my toddler is such a creative kid but now he plays with this everyday. Making animals, cars, ships and trees. Only thing is lacking are wheels. I wish this set has it.

*by S***M on 4 July 2021*

Our 2 year old is having a great time with these. Although I think the price is a little steep for the amount of pieces you get, my little boy is having a great time playing with them. It allows children to really use their imaginations to connect them together and build different things each time. However I will say I feel once you build a little top heavy or try to pick your design up, it doesn't take much to break apart. Not much of a big issue though, they're great fun.
