Another one brooch thing that even lights up, but can be worn without switching on as well.
Was dreaming about it a long time, now finally it is realized. Crazy!
All the batteries are hidden under the crystals. Lights don't warm up, shine bright more than 14 hours. I was testing them and run out of patience. Long enough to cover the festival or party.
It even doubles as wireless interior lighting and could be pretty sweet party decoration that looks like explosion of icicles.
I will count it as number 7
