1, colorful stick is a new type of painting supplies. It first appeared in Japan, and later the technology was improved by South Korea. After the introduction of China, some enterprises made technical improvements. Colorful sticks generally have a plastic shell, and most of them rotate in lipstick style. Compared with traditional crayons and oil pastels, color pastels have less resistance, better coating, better water-soluble effect, easy coloring and less slag dropping, and can easily make oil painting and watercolor effects.
2. Colorful bars are new products in China, mainly divided into 12, 16, 24 and 36 colors. According to the technology, there are two kinds: ordinary smooth and super smooth moisturizing. Compared with ordinary products, super smooth has higher smoothness, better coating, better stereoscopic effect, better water solubility and higher durability. Due to the price of raw materials and technical reasons, most of the products in the domestic market adopt ordinary smooth types, such as the colored stripes of Lemei True Color Crystal and the colored stripes of Guo Yun Sunshine Angel. There are few enterprises that produce super-slip. Due to technical problems, only two or three companies in China can produce ultra-smooth sliding products.
