I'm not sure of the length sorry. They are are around the same length. If I was to put 1 of them on it would then it would reach my breasts. It don't come with a gift box sorry. They are brand new. I bought them around a year or 2 ago. I was going to purchase silver charms for them to sell them on but never got around to it x
I'm not sure how to use GIN sorry. I would certainly consider it though. If you know how to then could you let me know please. Also how much GIN was you thinking? X
