I know the clasps on these two perticular bracelets look like the screw together type, but they're magnets (and I'm mentioning this frist sort of as a warning). They're very strong magnets - so when you take them off, you need to slide them apart, not bend them seprate, or you risk loosening the magnet's seat, and having them come out.
This also serves as a warning, because this isn't the bracelet you want to wear if you often hit you hand against something - as it'll come off and you'll never know of it until it's too late to find the bracelet. >_< ::dissapointed sigh:: They're awesome, very beautiful, but I don't want anyone else loosing a bracelet like I did, so I'm warning y'all about it here. Becareful with hitting your hand wearing these; it takes some force to get them off, but still...
Anyway! These bracelets are made with Swarovski Crystals inlaid within metal bases, some little seed beads are used as spacers between the other crystals - and that's about all they're made with ^_^ besides the metal wire, but you can't see that so ::shrugs:: ^_~
