With the average cost of a Lego brick at 10.4 cents, a question you might be asking yourself is why legos are so expensive. Lego claims this is a result of the quality and safety of their bricks. I'd say that this is somewhat true as in their category, their quality is unmatched. They build a product to pass from one generation to another and do so with expensive plastics and molds.
Those building blocks are Chinese replica and much cheaper alternative of the expensive Lego blocks, but they still got full certification and used eco-friendly plastic, so you should not worry about the quality nor the safety.
