This is a popular necklace from Crío. I used to wear it until last year, but I'm selling it because I switched to Colantotte and no longer use it. I've been using it since my university days, and I had the color changed to make it like new around January of last year. After that, I had it cleaned about six months ago and used it, so there is some wear and tear. The connection uses a double lock. Please note that there is no box.
