I can lend 2:1 for GBC or a dyeworks potion each if I have extra boxes.
The items here are not up for trade.
Here are all of my UFT items.
I usually also have GBCs to trade, as long as you don't mind which one (all cube-type)
If you mail me to trade, please make sure you list what you actually want in my trade list. If you don't, I will assume you don't actually want to trade.
