The quantity of each item represents the suggested cap value, according to /~Valentine.
12 = 1-2 GBCs
23 = 2-3 GBCs
34 = 3-4 GBCs
These numbers are only suggested, however. I'm happy to negotiate a trade if you see something you like!
These items are up for trade in exchange for one (1) GBC or some equivalent. I'm also happy to do 1:1 Faerie Quest Fortune Cookie, Lab Ray Fortune Cookie, or Dye Pot.
