How much can I buy a six-character mantra pendant in kind?

The six-character mantra pendant has a deep market, and the prices of common products are generally below RMB in 200 yuan. If you don't have the ability to distinguish, try to go to an old shop like Fochenxuan, and it's best to go to official website to be more authoritative. Anyway, I can't believe what's in a treasure, so choosing a brand would rather be more expensive, at least rest assured.
