Hey Acid Trip. Thanks for ordering a key from my store.
To clarify a few things...
The storm trooper key made by GirlDC is cast and electroplated sterling silver. Being semi-precious they retail for close to $100. That is before you factor in re-sale value due to rarity. I recently purchased a ghost key
it's cute but was a wallet breaker.
The Trooper in the charity auction is not publicly available. He's not quite sure what to do with it yet.
Making licensed figures into keycaps for profit is not on everyone's to-do list especially since Disney bought the Star Wars franchise. There is a lot of risk for small time guys like me if we make the wrong moves. If you see something like this expect it to be very small and over quickly. This is to avoid getting the wrong kind of attention.
I hope this info helps more than it discourages you from looking. I just hope you understand it will not come at a low price.
