Not sure what they are used for, but they seem to hold light very well.

If you are building a luxury shower or bath, these wierd peices would be amazing built into the wall to let light through.

What are they? Who made them? We are not sure, but they are amazing.

These are thick and are very heavy, we will package them well.
