Bought this originally with the intention of modifying an OAG to upgrade it to a 12.5mm prism. However decided to scrap the project and prism was never used. So aside from the package being opened, it is brand new.
Specs of the prism can be found here :-

This is a high quality prism with an angle tolerance of +/- 15 arc sec, surface flatness of λ/8, & surface quality of 40-20. It's a 12.5mm prism. AL & VIS 0deg coated.
You can see that I paid $194.33 (shipped) but I'm looking for $170 shipping included (within Australia).
