OVJ STEM Building Straws Geometry Set x 400

This 400-piece building straw geometry set offers a structured way for children to explore shape construction through lightweight plastic straws and durable multipoint connectors. Each box includes coloured straws in four lengths and a range of connector types that lock securely, allowing stable 2D and 3D forms to be assembled. The components are designed to help young learners understand spatial relationships, simple engineering ideas, and basic geometry through hands-on play. The set also comes with a printed guide that illustrates joining methods and model examples, making it easy for children to start building houses, towers, and imaginative structures. The straws are smooth, safe for small hands, and sized for comfortable assembly, while the connectors provide firm friction-fit joints that support repeated use. This kit functions well for home use, classrooms, makerspaces, and creative play environments where children can experiment, problem-solve, and construct models that reflect their ideas.
