5970 Original Chang Hardware, all of them are thickly gold-plated. You can zoom in on the pictures to observe; the surface color of each metal part is very uniform and pure, giving it a precious metal feel. This is something that artificial coloring processes cannot achieve. Most hardware on the market is artificially colored; the cost difference can be dozens of times. Market hardware tends to have a bluish tint and lacks this precious metal effect. Even those that claim to have real gold plating don't have the uniform color of the original hardware.
