This accessory box contains 12 magnetic Magformers triangles in a solid white colour which contain free-spinning neodymium magnets safely sealed in every edge. The pieces have white fronts and crayon colour reverse sides (in red, yellow, blue, pink, orange and green). The pack is the perfect stocking filler or birthday present for any child who has an existing Magformers collection - as you simply can never have enough triangles! These ‘crayon colour’ pieces are ideal with the My First Set lines, but pieces are compatible with every Magformers set in existence. Other 12-piece box sets include squares, pentagons, hexagons, diamonds, rectangles, super triangles, isosceles triangles, etc - all the main Magformers building shapes.
