My son like but he found it little complicated because of the color of each piece is Black.. So difficult to found ans recognize different pieces

### ⭐ Bad quality
*by M***A on 8 April 2024*

I’m disappointed with this set. The pieces don’t align well, making them difficult to connect securely. There are noticeable gaps between the parts, which has been frustrating for my child. Whenever he manages to attach one piece, another tends to fall apart, leading to a less enjoyable building experience.
