Pins with Quicksand are mainly composed of two parts, one is the external pin base, which is usually made of metal or plastic and has different shapes or designs to suit different needs and themes; the other is the internal transparent shell, inside the transparent shell, filled with coloured sand or special pigments. When the pin tilts or shakes, the coloured sand flows in response to changes in gravity and motion, creating a charming quicksand effect. In the process of filling the coloured sand into the transparent shell, precise handling and high-quality materials are required to ensure the smooth flow of coloured sand and long-lasting. It can be applied to Multicolour occasions, such as corporate activities, school commemorations, community organizations, and so on.
