A brilliant inventor had an idea 20 years ago while having dinner with his family one November night. He noticed something on the table and thought he could easily produce a plastic version of it for everyone to enjoy... And he was right, the product became so successful that even Sears tried to copy his idea, resulting in a lawsuit that made him 1.7 million dollars.

Today, his company makes 30,000 of these every single day... What is the product?
