It is helpful and pretty, too.This is not sturdy. It is weak plastic. I wish I had gone with something else and will probably have to replace them soon.The class does not hold tight the closure is very loose and that’s the whole point of buying this is for the actual clasp on it do not waste your time and buying this flimsy cheap product that does not hold a class but I will be returning thisIt clearly says, "Shaft and Clamps are made of all metal". Bulloney! These are made of plastic! All of it including the clip. If you're using this for smoking, you'll melt the plastic when the heat gets to the clip! Might work okay for putting on jewelry, but they seem awfully weak for that. I would not have bought these if I knew they were plastic. Don't buy these pieces of junk!No metal, all plasticDid not hold the joint at all. Clip is way too weakThese are great roach holder. Very pretty too. I haven't tried it will bracelets yet
