Smoky/Blurry Surface - Science Education

I received the prism and took it out of the box and the surface was blurry on all three sides.

There is also a small scratch on one side. Since I will be using it for photography I would like the prism not to have an annoying haze like this. Please see the attached pictures to see the defect on the three sides of the…

Pros
  • Shipped very quickly
Cons
  • Crumpled

A great educational tool that easily explains the basics of…
