The Lego pieces are too small. After fitting the pieces, 4 year olds cannot detach the pieces on their own.
Legos fit together very well but they are not really value for money toys.
Considering you know about the size and price, and want to buy Legos like I did, buying from Flipkart is a good idea.

it is nice toy set

Ma girl love , Lego always in higher price side

Very very small pieces
Disappointed useless for a four year old
