Geomag Magicube 4 Shapes Recycled Bulk set contains 128 magnetic construction pieces designed for creative building and educational play. This comprehensive building system features four distinct geometric shapes that connect magnetically from all sides, enabling three-dimensional construction without limitations. The magnetic cubes, rods, panels, and spheres are manufactured from recycled plastic materials, supporting environmental sustainability while maintaining the durability and magnetic strength Geomag is known for. Each piece measures approximately 2.5 cm in diameter or length with powerful embedded magnets that provide secure connections for complex structures. The set includes multiple color variations in vibrant primary and secondary hues, encouraging color recognition and pattern creation. With a total weight of approximately 1.2 kg, this bulk set offers substantial building potential for individual or collaborative projects. The magnetic construction system develops spatial reasoning, fine motor skills, and problem-solving abilities through hands-on experimentation. All components meet international safety standards for children's toys and are compatible with other Geomag Magicube systems. The recycled plastic construction ensures long-lasting performance with smooth edges and consistent magnetic attraction. This educational building set supports STEM learning principles through open-ended construction possibilities, from simple geometric forms to elaborate architectural designs. The magnetic connection system allows for easy assembly and disassembly, promoting repeated use and creative exploration. Suitable for various age groups interested in construction and magnetic play, this comprehensive set provides extensive building opportunities with its diverse shape selection and substantial piece count.
