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 Elmito Yeager

We use prisms in the classroom to study light. They are beautiful. With the first delivery there was a problem with the packaging, one prism had a broken corner. After contacting us, the return was accepted and a replacement was delivered immediately. Excellent customer service.
