The 142pcs STEM Educational DIY Building Blocks Kit (SKU BB265272) is a blue-and-red connector set that snaps together, comes apart, and rebuilds into whatever a child designs. Each kit holds 142 pieces, packed in a storage box plus a color box at a package size of 25.5×15.5×13 cm. For importers and educational-supply buyers, the verifiable core is simple: a defined piece count, a stated connection mechanism, a documented sales unit, and named approval evidence — everything needed to slot the SKU into a construction-toy range without guesswork.
How the set works
Pieces connect by snapping together, so the same 142 parts move between free-build models and rebuilds. That single mechanism is what places this item in the Creative Connectors category: the play value sits in joining and re-joining parts, not in a fixed model or a one-time assembly. Blue and red pieces give the kit a consistent two-color palette across the range, and the storage box doubles as the piece container between sessions — a practical detail for classrooms, playrooms and retail display alike.
