I have had this necklace for 2 years now and never took it off. I actually sleep, bathe, eat, workout, swim everything and its still in tact and my neck haven't turned green. i have the Alison font style I don't know if they still have it I've been looking for this website cause so many people ask and i found it today and I just had to leave a review because i love this necklace!!! 10/10 recommend (shipping just takes awhile totally worth it though).
