The salesman sweated a bit, giving a rather crooked smile at their responses. "N-nicely done! You were able to spot something fishy about these artifacts! You see, it was all an act to test if you have the eye to see through scammers! You know this place, full of scammers, tricksters and people trying to get the last golden coins, you see?" He swallowed his saliva and coughed a bit as he turned his back on them for a second. "Damn, just my luck! I was just trying to get a couple of bucks, but I got bitches instead of witches!" He cleared his throat, took a deep, quick breaths and turned around with more violins in hand. "Well, ladies, since you pass the test of these fools violins... here's the real deal..."
He opened the box and pulled out several violins that were made from some unknown material. "This particular item is rather unique! With one musical note emitted from this device, you can able to turn anything into objects!" He explained. "Of course, I have the violin in question, but this is precious you know? Rarely anyone would ask such a thing without showing me some gold."
