That makes sense. Particularly since the acrylic one could be easily "restored" after handling with some Novus polish... that would be a bit harder with the glass.
It's a hard call to try and figure out what the "broader" market would want. We're pretty handy here so a little Novus polish is no big deal. Not to mention, if it's sold as a paperweight/fidget type thing acrylic would definitely make more sense. But are "they" even going to be handling the item?
Would the glass ones be harder to ship, perhaps? I remember the glass Dark Crystal shards from the RPF seemed to have scratch/dent sales from time to time. They still looked great but had tiny chips or scratches due to the travel from the factory.
