Review on 👓 GloFX Cardboard Diffraction Glasses with Paper Lenses by Austin Arvayo

We have some paper "glass fireworks" that are 10 or 15 years old. Old glasses require you to look directly at the light source. Rainbows appear everywhere you look. They are sharp, shiny and plentiful. These glasses I ordered from Revain are pretty lame in comparison. You have to look straight into the light to get some faint rainbows - not at all what is shown in the picture. The children seemed pleased with their efforts on July 4th. But I was extremely disappointed.
