We talked about these very pieces quite some time ago, I think it was Sunhuntin that found where they are from but I may be mistaken. I remember these as a few years ago I also received a couple of these and ended up throwing them away because I thought they were from a knockoff set. I look around.
This set has 4 of them but its not the set I remember. Maybe they came with more than one? https://www.youtube.com/watch?v=2V1UmA-f-Tw
