A Crystal Sphere
The mages went predictably compulsive when they saw this, detecting magic before anyone else in the party could do anything.
But no dice, disappointed they walked away without giving it a second glance.
You too almost walked off, until you realized that a head sized perfect crystal sphere on a platinum display would have to be sold in a larger town, because no one locally could afford it. What's more, it's even easy to carry!
Now if you just could relax and stop thinking you're going to drop it.
