Review on Optical Crystal Photography 4-Pack for K9 Enthusiasts by John Larsen

They are beautiful. I bought these for my son who is studying geometry and he absolutely loves it. The set is packaged in a beautiful black satin lined box with space for each item. We study forms together, and soon we will add to the study of how light passes through them. I showed my 3 year old son how to make a rainbow that reflects the sunlight and he loves it! I love how the box turns them into precious, precious treasures that my kids automatically knew to handle with care. They are a good size, not small. As soon as we start taking photos with them I will update our "masterpieces"! :)
