Not secure
"My mom and I both bought these bracelets to give to each other. I was going to put a charm on mine, but decided to wait. Immediately, i noticed my bracelet opened up twice and then a third time. I took it back and they replaced it with another. I noticed the ball on this one sat higher. I've had no problems with this one. My mom now noticed hers is popping open too. Thanks to James Averys great return policy, I will exchange hers next time I visit. This appears to be a design flaw. Beautiful simple bracelet, but not worth the risk of putting a charm on it."
