Half a year of preparation finally brought us this unprecedented product. Lithography platinum-Curved Mirror The world’s first playing cards product using lithography technology achieves a flat three-dimensional effect of curved light refraction without texture through photolithography technology. In this way, it has changed the embarrassment of using holographic laser instead of mirror effect in previous products. The new process does not increase the thickness and does not negatively affect the hand feeling. The narrow white edge design increases the display surface of the open fan, and the center curved mirror design has a noticeable effect on the rotation action. The dot is 1 for the solid and 0 for the hollow, and there is no corner mark. Keep the point recognition while making the cards in the process of movement.
