 Dating back to the late 1960s, the founder of Sunkee Envelopes Limited ([SunKee"), Mr Au Moon, started his apprenticeship with a local envelope manufacturer in British Hong Kong. Back then, one`s craftsmanship was much valued in the machine-free era. Since all envelopes were hand-made, the skills level certainly determined the quality of the final products. Although the salary was meagre and the working hours were extensive, Mr Au`s hard-work paid off by mastering all the techniques required. During the few years of apprenticeship, customers gradually recognised Mr Au`s refined quality of work, which gained him his popularity and high reputation. Upon Mr Au`s completion of his apprenticeship, he founded Sunkee in 1975 and began its journey as a leading envelope and manila folder manufacturer in Hong Kong. Followed by the opening up policy of China in the 1980s, Sunkee set its milestone in successfully industrializing the business in modern manners. Through purchasing new equipment, it transformed from handmade production to semi-automatic machinery production.
