This is definitely the longest mass-produced shining device. It is 58 cm long, and each has a link to connect it and put it e.g. on one´s neck. It is possible to produce a very interesting effect by not connecting it and swinging it in the air as if with a long shining string. It is thicker than an ordinary bracelet, and that is why the time of shining is definitely longer and the light more intense. We recommend it especially for all kinds of parties, discosas well as birthday parties and other events.
