Just so anyone else doesn't make the same mistake as me. Dragon scales from the Item Mall are trade able and can be sold in game. Dragon tears are not. Maybe this is common information and I'm just out of the loop but if you are planning on selling an item from the Item mall to make some quick gold, save your CC and don't buy the tears.
I'll admit it can be confusing because some item mall items says they're tradeable, some says they aren't tradeable, while others just doesn't say anything about trading.
