What is this chain called, and where can i buy it?

it looks like a ball chain necklace. they come in all different sizes super small normal size large and there are some ugly super big ones. i like the smaller ones i have like 8 of them some are silver some are red and some are black. i got mine at claires a while back but you can get them at like target or walmart or anywhere if you go to the jewerly section. they are pretty much at every jewerly store.
