Unfortunately, most Kiddi-only toys made of plastic .... Such puzzle, building blocks etc. are simply WOOD !!! It's a great material that does not go so quickly broken and usually you can fix it while you throw away the plastic stuff - this they are often much more expensive ... I had such a wooden puzzle of my kids (that is already 25 years old ) and "nothing to it", just become a little darker, so you can inherit more! Therefore, I would not hesitate to buy again such puzzle and building blocks made of wood !!!
