Thank you for viewing. New, unopened Magformers Basic Plus Set, 30 pieces. I purchased this and stored it at home without using it. It's new and unopened, but the box has some scratches. Please check the photos. This is an introductory set that allows you to enjoy playing with equilateral triangles and squares. You can enjoy curved expressions using circle and round window parts. Not only equilateral triangles and squares, but also pieces with holes in the middle and circle parts are included, allowing you to create more concrete images, such as using them as windows of buildings. By connecting circle parts to other straight parts so that they stick out, you can assemble three-dimensional and unique works. By arranging squares horizontally or stacking them high, you can go back and forth between planes and three dimensions, expanding from shape play to construction play and three-dimensional motif creation. Equilateral triangles change shape, forming a rhombus with two and a trapezoid with three, deepening your understanding of figures while playing. #Magformers
