Disowned by his father for not pursuing law as intended, Cardano faced financial hardship. He relied on his mathematical talent to gamble, and after earning money, he constantly worried about theft. This led him to research various mechanical devices, eventually inventing the combination lock. He also developed many other mechanical devices, including the famous "Cardano's suspension." **➤ Product Details** Difficulty Level: ★★★ (5 stars highest) Assembly Time: Approx. 1.5 - 2 hours Recommended Age: 6+ years Included in Packaging: Illustrated assembly instructions Product Dimensions: 20cm x 11cm x 23cm Package Dimensions: 30cm x 23cm x 3.5cm Material: Non-toxic wood Origin: Taiwan **➤ Precautions** • Please use the provided sandpaper to smooth wooden parts before assembly.
