Review on 🔍 Cedilis 2-Pack 6 Inch Light Optical Glass Crystal Triangular Prism: Enhance Light Refraction Spectrum Learning, Unique Photography, and Science Physics Teaching by Athenasby Whitney

Bought these for my kids to experiment with the principles of light reflection/refraction. Too heavy and sensitive for children. Easy to break and hard to make a rainbow. It is only broken at a certain angle. Expected better quality for this price.
