Neomails are always welcome; the worst I will reply is, "No, thank you."
I like these items, and I do use them, so I won't be in any hurry to trade them away for 1 GBC, but I know it can be difficult to find the ~1-2 items you're seeking sometimes, and I don't mean to hoard these ones away forever.
So don't be shy about offering on these items, just know that I value them toward the higher end of their spectrum.
I probably won't trade these items away readily, but you can always offer. I don't mind if you offer.
