[SK Comparison Data] We compared the transparency of three types of photos. The comparison was made with 1t (mm) at SK's internal facility. As you can see, the ultra-high transparency clear sheet is very transparent. Can you see it? Even though it is placed over the photo, the ultra-high transparency allows the photo to be clearly visible! The clear sheet in the middle is indeed different when compared to the ultra-high transparency clear sheet, but it is still sufficiently practical depending on the application! It is a clear sheet material that meets transparency standards. As a value sheet with excellent cost performance, it is widely used in various fields. At SK, we specialize in the sale of these three types of sheet materials and molded products made from silicone materials.

We support the development of original products that can be used by people of all ages and genders. SK primarily engages in completely original made-to-order production, starting with receiving drawings (manga illustrations, data), model types, masters, etc., from users to initiate mold construction and product manufacturing. We provide a total service business that responds to various requests, including resin molding, rubber cutting processing, and integrated molded products, delivering peace of mind and quality products to our customers. However, we have also received many inquiries about whether there are ready-made promotional items available. The reasons for this include: 1. It is difficult to create from a mold. 2. Ideas are hard to come by. 3. The long journey from idea to data processing to prototyping to delivery and completion... These are the main points raised. In response, our company has been developing unique promotional items full of originality for several years, successfully optimizing cost performance with the know-how we have cultivated over many years, and we have also worked on the development of various daily necessities, such as the Caprin. While we cannot introduce various examples due to regulations, we would be delighted if SK's creativity and processing technology could be of any assistance to those engaged in product development that brings joy to customers.
