Review on 🎄 Sparkling 4 Pack Light Up Necklaces: Bulb Ball Star Christmas Lights for Adults and Kids - 39" LED Necklaces for Festive Christmas Decorations by Hesham Peltier

It's fun, bright and very Christmassy. They all have a different shape, but are all the same length and have the same switch. You can pull them apart (make them into one long strand) or just pull them over your head. The power button is a little button that's hard to find when it's behind your head, so let's turn it on first. When turned on, there are 3 modes - flashing (each flashes differently), flashing in unison, and steady. A necklace that is spheres with holes could possibly cause the right person to have a seizure in flash mode as it is quite bright and those holes multiply the light. It's a cool effect, but looking at it can make the wrong person sick (in the blinking or steady state, it's normal).
