These are a super rare find. I haven’t been able to find just the set of these anywhere online. I’ve seen lamps with them in it but just the lamp is being sold. So I called a few auction houses locally and one was able to have me send them pictures and they were able to tell me this, they haven’t seen a set of these in over a decade and the last ones they sold over 10 years ago sold for $450 for the set of two. That is why these are priced as high as they are which is still a bargain.
