Buttons can be made of plastic (resin, plastic), metal (copper, iron, alloy) and natural (shell, wood, coconut shell, bamboo). Buttons are made from different materials using different processes. Some of the buttons look the same, even to the eye of an industry insider, so you can only scrape off your coat if it's broken.

For example, plastic resin buckles and plastic buckles (including all kinds of plastic) are usually die-cast, so there is a line at the edge of the buckle. This line may be removed by some factories in subsequent processing, but it is lighter than resin (some plastics are heavier).

Resin clasp carved and polished by automatic clasp machine, so the surface is not full of mold line, very smooth. But it's fragile, scratches its surface easily, and softens when you put it in boiling water.
