Review on 🌈 Optical Diffraction Grating Peepholes by Rainbow Symphony by Jose Mcdaniel

I love to keep a few trinkets in my pocket or purse in case nearby kids throw tantrums at grocery stores, planes, restaurants, etc (of course, I always get parental permission!). It's SO BIG for handouts. They are essentially cardboard monocles made from the same material as the "Firework Goggles" sold around the 4th of July. When looking through, each light source turns into shimmering rainbows. The kids love them and if I ever get blue I blink into one of them and the rainbow really lifts my spirits. They are amazing!
