Hello, I am trying to get any information i can on my set, The markings under items have chinese 5 symbols that translate to " China Jingdezhen" and under that say "made in china"
These as u can see are in origional box and in excellent condition.
Any information on these would be great, esp if soeone knows there value.
ThankYou
