It's one thing to say, "this is yellow" or "that is a triangle," but to actually hold it in hand, examine it from every angle, and combine it with corresponding shapes, helps children understand the very nature of the object or color in question. This is how they learn geometry and the basics of STEM education.

You want a safe toy for your child with smooth edges and materials according to international standards. You also want a toy that will "survive" all the banging, throwing, and being stepped on. 

Many toddlers had their way with this toy, and we haven't heard a single complaint. So, this is the toy you are looking for!
