If you are a collector, this might be a nice chance to get a genuine Farscape prop. Giti just put up her Chiana contacts for sale on gumtree.
Here is what she said about it:
After contemplating about it for awhile now, I've decided I don't have any use for them anymore as they are just sitting in a closet collecting dust. I would much rather have them go to a good home ...where they can be on display and well loved.
If you always wanted to have the original Chiana contacts in your collection, here is your chance.
