Wish they were cheaper. After tax, they cost about $0.50 each. We gave them out to little kids on Halloween. The older children got sweets. These are really beautiful rings with 3D texture and beautiful color. They flash beautifully and brightly; Red and blue alternate. This is a good safety device as cars can see it from a block away. Some of them glow in the light even after charging. It was a nice little surprise. We haven't had a wedding yet, having given away about 60. We have a few left and hopefully they'll still be working next Halloween.
