In the absence of Dando, I've stocked up on a few more materials than I really want (plus I WTB Castle Crashers for a good friend of mine from this guy: http://forums.spiralknights.com/en/node/87996 )

My prices are based off of sale prices done in Haven and through the AH. We can trade in-game or over Steam. I only ask you to tell me how much of each mat you want before-hand so I can calculate the amount before the trade is done. Also, if there isn't a material on the list, be sure to ask. I may have it by the time the trade is done.
So here are the materials I have up for sale and how many I have on stock for fast trade:
