Such a keychain has a strong three-dimensional effect, bright color, and strong visual effect. It can be customized according to the size and shape you want, but the color is easy to become dull.
2) Acrylic
Acrylic is also called plexiglass. Because it is transparent, you can put colored paper in the middle to make keychains of different styles. The hardness of acrylic determines the degree of wear and tear of the keychain, and the bright colors can meet the individual pursuit of different tastes.
3) Zinc alloy
Generally, the metal keychain made of zinc alloy will make the whole product more beautiful by dripping paint or electroplating on the surface.
Because zinc alloy has excellent plasticity, does not stick to iron during die casting, and has good fluidity, more and more keychains are made of zinc alloy. The improvement of its material also increases the practical and aesthetic value of keychains. At present, the surface of many zinc alloy keychains will be electroplated with a layer of metal, which makes the shape of the whole keychain more beautiful.

All kinds of wood are used to carve into various patterns, and some are also engraved with blessing text. The more common types of materials are: rosewood, jujube wood, ebony wood and so on. Among them, jujube wood is believed to have the effect of warding off evil spirits in Taoism, so it is used more. (Although peach wood also wards off evil spirits, the wood is relatively soft, so it is rarely used as a keychain.)
