The Mobilo Construction Set (424 Pieces) Plus Gratnells Tray and Lid is an expansive, commercial-grade STEM resource designed to inspire open-ended engineering, spatial reasoning, and cooperative building across primary classrooms, day nurseries, and early years foundation stage (EYFS) settings. Packed with 424 high-impact components—including geometric building blocks, flexible connectors, axles, and specialised large wheels—this comprehensive kit allows large groups of children to construct complex moving vehicles, animals, and architectural models simultaneously.

Engineered for small hands, the brightly coloured squares and cubes clip together securely with minimal effort, allowing children aged 3 and above to transform abstract 3D concepts into tactile creations. The set includes 12 extra-large wheels (74mm diameter) alongside 16 double-sided work cards structured across three levels of difficulty, providing guided construction challenges that cater to varying developmental abilities while promoting self-directed learning.

Housed in a heavy-duty, stackable Gratnells shallow storage tray with a clip-on lid, this set keeps busy construction areas organised and ready for daily use. Crafted from non-toxic, highly durable, and 100% washable materials, every component can be effortlessly sanitised between group sessions to maintain rigorous hygiene standards in shared educational environments.
