Prism Set, 4 Pack K9 Optical Crystal Photography Prism Set, Include 55mm Crystal Ball, 50mm Crystal Cube, 50mm Triangular Prism, 60mm Optical Pyramid, Gift Box for Teaching, Science, Photography, Play

i use the glass forms at the base-culminaion of a community patio fountain----perhaps 50-60 of these forms make up a pile about 1 foot circumference base. i've collected them four at a time as money permits. so we're talking approx. 1' diameters an 1' height at base. and 4, 8, or twelve will mark completion.

Great for any kid that loves science.

Very cool

I like the entire set, all are high quality. The set arrived on time, well packed and in A1 condition. The set comes on a nice box to store the prisms safely in. This set would be good for teachers, photographers and anyone that enjoys playing with refracted light.

Did not come with any cracks, i was even too scared to touch it because I did not want fingerprints on it. Keeping it as a decoration in my office because it is very nice!

Perfect gift

I didn’t expect much as it was kind of cheap but bought this and the 1st had a major chip on the pyramid piece on arrival and returned it for a new one. The 2nd which looked slightly better still had a crack that was from the inside. Both were visible I would buy a better option next time as there is no real QC with the wrapping looking for damage.

Super cool for kids or paper weights in your office
