I've got a set of Pirastro Obligatos that I'm looking to trade for either Innovation Super Silvers or Sliver Slaps. Or I suppose I could buy the strings outright, but I'm hoping not to spend too much, so unless you can give me a good deal, I'd prefer trades.

Not that I'm interested, but are they new?

I got them used, but only used them myself for about three weeks. I don't think the guy I got them on had them too long.
