Different varieties have different prices. The cheap ones are ordinary yellow horns and buffalo horns, while yak horns are more expensive, depending on the workmanship. It's good for you to spend 30 to 50 yuan yourself, but you have to realize that there are many rough products now, all of which are made of expensive scraps and then polished. This kind cracks easily, which is not good. Also, if it's yak horn, the darker it is, the more off-road.
