4 Pack K9 Optical Crystal Photography Prism Set, Include 50mm Crystal Ball, 50mm Crystal Cube, 50mm Triangular Prism, 50mm Optical Pyramid with Wiper Cloth and Box, Photography Accessory for Teaching

Doing some home science projects with the kids, these came in the post quickly and were good quality. Really good fun with photography and laser projects. Happy with the purchase.

Here’s an inexpensive and pretty way to dress up that one super sunny window sill.All of these prisms are crystal, the sphere is acrylic, but it’s very clear.I’ve seen no bubbles or waves, it’s a nice mold.

I like all the different sizes these came with. They were a little pricey but overall seem like a good set.

I ordered these to do some experiments with lasers to show my children. These are above my level of expectations. The price would lead to believe they are going to be decent quality anyways. I have found no imperfections in my crystals. Packing is well done to ensure the safety of the items and I will use this packaging for permanent storage.

Çool set. Decent quality besides my pyramid was received with a chip out of the top.

Well made and heavy for its size. Work well for light experiments

2 shipments, both are garbage with bubbles in the glass and one arrived broken. Advertised for photography, but there are bubbles and imperfections in the glass, soooo how is that good for photography. Also comes from that one country that produces garbage of course.

These prisms are beautifully packed and so much fun to use in photography. You can reflect rainbows or use them for fun reflective effects. One had a surface ding and another had a bubble in the glass, but nothing that would affect the reflective or refractive qualities.
