The original shining party bracelets will brighten all parties and celebrations. It's a plastic bracelet that can be connected with a connecting piece. It has chemicals inside it to form cold light for 4-8 hours. The bracelet is activated by breaking over the whole length of the bracelet and thus merging the chemicals. Then the bracelet lights up. The lighting time is about 4-6 hours - the lighting time can be extended by cooling the bracelet in the fridge.
