NWOT Third Eye Pinecone Light Up necklace

Size MEDIUM/LARGE - (see picture compared to quarter) This necklace has never been worn. There are absolutely no flaws. I am unsure what the stone is. The stone lights up by turning a small knob on the back (pictured), or by pressing it. The "knob" creates an on and off setting. There is a very slight dimmer effect. The pendant is currently on a 18" black leather cord/necklace. I will include a 2nd necklace. Upon request, for NO extra fee, I can include a strand of suede/leather cord. Size optional Cord available in: black, dark brown, light brown, chestnut, tan Reasonable offers accepted
