Magformers Tileblox Rainbow 20-Piece Set brings you a creative magnetic construction toy with semi-transparent magnetic blocks. Magnets are fixed in the edges of every piece, so children can build models in 2D and 3D with this 20-piece set containing 12 squares and eight triangles. The Tileblox set helps children to understand spatial awareness and stimulates their senses by allowing light to shine through the pieces and project colours on to surfaces. When playing with Tileblox, children can make flat 2D shapes as well as more complex 3D geometric shapes like cubes, tetrahedrons, octahedrons, pyramids and prisms. As they play and build, they can learn the relationships between different shapes, the properties of shapes and more.Pack size: 21.5 x 18.4 x 3.5cm (8.5 x 7.2 x 1.4 inches) 20-piece set with semi-transparent shapes in six different coloursSTEM toy with eight triangles and 12 squaresRobust construction with ferrite magnets in every edgeSuitable for ages three years and over De
