Review on 📸 Exploring the Spectrum: Triangular Photography Experiments for Teaching by Derek Faseworld

Made a rainbow which was my main goal. The weight is good and it feels like a solid product. But one of the prisms is cracked inside (smooth to touch but looks tactile). And I was disappointed with the packaging. The red decorative box it came in was sealed with tape and ripped when I opened it. For the price I'm happy to get a decent Prism but I could be happier. Instead of keeping two crystals in a padded display case, I just leave one on a separate shelf.
