Figure 8 Jump rings?

[glitterophelia.livejournal.com]

Okay. I sent my husband to the bead shop to acquire some jump rings for my charms (see my previous post this morning), and he came back with two baggies of figure 8 jump rings, which have no opening to pry open to put something on them. I tried googling them, but pretty much all I found was how to MAKE them or sites to buy them at. Anyone know what I can do with these? I assume putting charms on them isn't going to happen. Husband got kind of annoyed with me when I asked him what they were for, he says "you asked for jump rings, I got jump rings." hee. Explaining to him that these weren't quite what I was after appears to be useless. Help?
