It isn't an unusual or an australium offer, but I do have something that might interest you.
I'm currently brokering a Pro KS kit for a friend. The kit itself happens to be for a Batsaber, and it is currently the only Batsaber kit in existence. Obviously, because it is the only one, there isn't a defined price, but my seller was wondering if you'd be willing to swap the Aussie RL for it?
If you want details, the kit's sheen and fabricator are Manndarin and Hypno Beam
