One of the most expensive items for sale by the market/guildmaster. Thus one of the best buy/resell profits but only sellable at normal price by stocking a vending machine with vending machines.(The 1.108 patch fixes this bug.) (Best to buy when the price is down for about 33,000 pix gain per machine)
Players are also able to sell these at a markup when customers approach Recette, requesting a Metal item.
