Then in 1978, the company was reorganised & registered to as a limited company and started to develop and manufacture aluminium alloy spectacle cases, for export to Western European, U.S., and Japan etc.

We firstly put our focus on production of traditional spectacle cases. The case is made of aluminium alloy. So is 2/3 lighter than the ordinary spectacle case. In addition, we offer different size and, if requested by the customers. We can also engrave logo on the cover. Therefore, the case is highly welcomed by the customers.

In 1991, we expanded our business and moved our factory to China.
