Eric Wilson is a father. To give his son Mark a better notebook to help him engage in his studies, Eric spared no effort in exploring the properties of paper. Three years later, he finally invented a paper with a smooth, durable surface that does not soften easily when exposed to water. He praised it happily." This paper is as precious as gold." Later, he founded "Regolden Book".

Regolden Book, which helps humans learn and work better.
