Hard enamel pins and soft enamel pins share similarities in appearance and application. However, due to differences in their production processes, they exhibit distinct characteristics. The production of hard enamel pins involves filling colored enamel powder into molded metal grooves, followed by high-temperature firing to melt the enamel powder and firmly bond it with the metal substrate. After firing is completed, the pins still need to be polished and ground to ultimately create a smooth, flat and fine-textured surface effect.

Due to the high-temperature tempering during the production process of hard enamel pins, the finished products have a harder and thicker texture, significantly enhanced durability, excellent scratch and wear resistance, and can maintain their bright color and exquisite appearance for a long time. However, precisely because of this relatively heavy characteristic, hard enamel pins are not very suitable for depicting overly complex and delicate design details. However, its advantage lies in the fact that it can offer a rich variety of color options. Whether it is classic and steady tones or bright and lively colors, they can all be accurately presented. With high quality, strong durability and elegant smooth surface, it has become the favorite of collectors who pursue exquisite texture and long-term preservation value.
