What is the function of a safety chain?

On a pandora or lovelinks charm bracelet?

if the clasp on your bracelet comes undone the safety chain will stop it falling off

Would my pandora bracelet look silly with just a few charms on it?

My boyfriend bought me a pandora bracelet and it has a few charms on it. Should I try to buy more…or is it okay to just have a few charms on it?

It is designed to be added to over time. My wife has one (as well as a necklace) and she has a number of charms that she has acquired over a two-year period. It is fine with a few charms. Shouldn’t the sentimental value that it has a present from your boyfriend count more than how many charms there are. Why not reserve the remaining room for special occasions where you will either get a charm for yourself or receive one from a loved one, thus increasing the special sentimental value that it has? (My wife will get another charm or two for Valentine’s Day).
