For item 13-1 is RMB 95.(USD 15.32)You charged RMB 97.
Because you want to the blade with long handle ,so ,we have to add 2RMB to each blade , the item13-1of blade is short handle .
Item 19,on you price list it is RMB 45 (USD 7.26) You charged RMB 67.
the item 19 , It just writes foil blade with rubber head for training,it RMB45 right ,but you want to them gold and with long handle, so we have to process them , the blade of gold need to add 20RMB to each blade and the long handle for 2RMB to each blade, so the total price RMB67
Hope you understand them .
Thank you !
