EISCO Advanced Acrylic Prism and Lens Set in Wooden Case (Set of 6) Shopper Reviews

High feature acrylic lenses. Safely packaged, so no chance of damage while shipping. I was able to exhibit to my 7 year old daughter the deviation/convergence of light rays by uncommon kinds of lenses, and the prism rainbow. She even detected the (weaker) rays that were reflected from outdoor/domestic surfaces of the lenses and the prism, and is excited about her discovery. We love the product.

I thought these would be dinghy. They are not. This drastically affects the skill to see bent light rays, making them reasonably a waste of time in my science class.
