I always buy a few of these whenever I make a purchase from The Psychic Tree. My sister wears her necklace 24/7, even for showering and never takes it off so she breaks her chains a lot. Since I started getting her these, she has limited her breaking to 1-2 per year which is great. Great quality and long lasting - I've had mine for a year+ and it's still in tact (I don't wear mine all the time).
Definitely recommend these
