Review: Great buy! - Great addition to the window! Exactly what we wanted and expected.
Review: Exquisite but Fragile - The Physics of light is the most spectacular, not because it the specialization listed on my undergraduate diploma. The dimensions of the pieces are perfect to use them as toys in natural light or in a lab set up. Unfortunately, the prism and the pyramid had a corner broken, each. I will patiently wait for the replacement. The packaging was designed to protect but it did not. I wish I could keep the cube and the sphere at a prorated price.

Great addition to the window! Exactly what we wanted and expected.

### ⭐⭐⭐⭐⭐ Exquisite but Fragile
*by S***L on December 9, 2021*

The Physics of light is the most spectacular, not because it the specialization listed on my undergraduate diploma. The dimensions of the pieces are perfect to use them as toys in natural light or in a lab set up. Unfortunately, the prism and the pyramid had a corner broken, each. I will patiently wait for the replacement. The packaging was designed to protect but it did not. I wish I could keep the cube and the sphere at a prorated price.

### ⭐⭐⭐⭐ Beautiful and well packaged, however the Pyramid shaped prism showed up broken.
*by P***S on May 13, 2021*

These are beautiful and nicely packaged, but unfortunately the Pyramid shaped prism was cracked upon arrival. I'll gladly revise my review upon replacement as this is truly a great value for prisms.
