142-Piece STEM Building Block Kit — Blue & Red DIY Construction Set
The 142pcs Educational STEM Building Blocks DIY Kit is a snap-together construction set supplied in blue and red, packed in a storage box with a color box sleeve. Buyers can verify the configuration before ordering: 142 pieces per set, a 25.5×15.5×13 cm package footprint, and a documented age span of 2 to 13 years. It is a wholesale building-block line, not a consumer retail listing — MOQ, carton and pricing fields are laid out below.
This kit sits in the Creative Construction category because the play mechanism is connection: the blue and red pieces snap together so children build DIY models they design themselves. That single mechanism supports a wide age range — younger builders start with simple shapes, while older kids work through more involved educational builds. For importers and educational-supply channels, that breadth means one SKU can serve multiple age shelves rather than three separate ones.

What's included
- 142 building-block pieces in blue and red
- Storage box for keeping pieces together between builds
- Color box sleeve for retail presentation
The storage box matters commercially: loose-piece loss is a common reason a construction set stops being played with, and a reusable box gives parents a reason to keep the set in rotation. The color box sleeve means the unit can move straight to a retail shelf without repackaging.
