Based on our experience in manufacturing and selling optical instrument cleaners for 30 years, we have been developing optical lens cleaners and household cleaners applying MICRO FIBER, a new material, and we established DAHMMI IND. CO. LTD. 2 years ago for export and domestic sales. Currently, we have sold about 200 million won and exported about 100 thousand dollars. We will continue to develop and export industrial cleaners. Microfibers are already exported to European and US markets, but we plan to export new patents and new products to Europe, the Americas and Japan. And we have already participated in many overseas exhibitions and are in contact with new markets and related buyers. Within the next three years, we expect exports of 5 million dollars and domestic sales of 2 billion won. We have also built a website, applied for overseas exhibitions, prepared samples of new products, and plan to export about 200 thousand dollars this year. We are also planning to participate in domestic TV home shopping, and the cleaner set for passenger cars has also been developed and we are in discussions with leading automobile companies in Korea. "Not stress, cleaning is also science."
