4 Pack K9 Optical Crystal Photography Prism Set with 50mm Glass Triangular Prism, 55mm Crystal Ball, 50mm Crystal Cube, 60mm Optical Pyramid for Teaching Science Physics, Playing & Photo Photography

These were ordered to verify a 3-D model. These are the real-deal and did the trick.

Came on time, in a black case. Pretty. As described

Smaller then I thought they'd be, but that was my fault for not reading the description better. Very clear and nicely packaged.

The media could not be loaded.  These are very impressive for the price.None of my pieces appears to have any inclusions, bubbles, or aberrations within. It's a very clear material. I've seen clearer stuff but generally only in lab-grade materials.The edges are *sharp*. These are very precisely made.They do show oil from your hands or other surface contaminants, but they wipe clean very easily. Keep a lint-free rag on hand to clean them, and if you need to handle them a lot, cotton gloves would be smart.The package is pretty decent. Each shape has a form-fitting spot. The inner container is styrofoam covered in some kind of synthetic cloth. If you're very picky you may want to keep them in something cleaner, but this is good enough for me.They feel sturdy but I'd be wary of subjecting them to any drops.

These are beautiful. I got them for my son, who is studying geometric shapes and he was absolutely wow'd. The set comes in a nice black box lined with satin and there is a space for each piece. We are studying the shapes together, and soon we will add in the study of how light travels through them. I've shown my 3 year old how to make a rainbow catching the sun's light and he is delighted! I love how the box makes them look like valuable, precious treasure, so my kids automatically knew to be careful with them. They are a good size, not too small. Once we start taking photos with them, I will update with our 'masterpieces'! :)

INLOVE ! Wanted these for photography at first but now I use them in my alter and I’m so happy I bought these. also great for in-depth kinetic energy & conversational piece.No complaints, wish they came in more shapes, bigger or smaller sizes and colors tho !

These are very beautiful. They came in a nice case. I was surprised by how nice they were. Very happy with my purchase.

This is a bummer I bought to take photos for a wedding this weekend and I unwrapped it to find a big chip right in the middle of it 🤦🏻‍♀️Wow second box was worse than the first. Super disappointing honestly.
