Polydron Kids Platonic Solids Educational Construction Set - Multicolored - Children Geometry 3D Shapes Building Kit - 4+ Years - 50 Piece Kit

Very good toy if your kid like to build shapes, the quality is very good, safe to use, colorful and good price.

I bought this to introduce my grandchildren to sacred geometry concepts. Initially learning how these connect was a challenge as they need a hard surface and to hold them carefully to avoid the shape collapsing, but they figured it out pretty quickly and enjoyed building with them.

Before giving a a gift to 6 year old granddaughter I tried it out. I do not think my very accomplished 10 year old grandson could assemble a 3D object with these. It is reasonably possible to assemble on a flat surface. Of course the problem is that 3D surfaces are not flat! Two pieces easily bend at desired angles or even three pieces, but more requires many minutes of frustration and failure followed by failure. It is too much trouble to return. Perhaps they can be used as shims.

No es bueno el ensamble de las piezas . Y no son suficientes las piezas

very sturdy build
