History and story : It was believed that silver would turn black if they came in contact with poison and therefore were used by emperors as a protection against poisoning. The desire for silver chopsticks and the poison-detecting belief spread to the aristocrats. The Emperors always feared their enemies were going to assassinate them an so food poisoning was one of those things feared. And silver will turn color when in contact with poisonous chemicals. So to be safe they all use Silver chopsticks and also had their eunuchs taste the food first. Item must return in the same condition that we send. Your feedback is very important to us.
