This pack contains two set of closures.  

The top one on the is a large rose type flower with a light rose Swarovski crystal in the center, and the second is a toggle with two light rose Swarovski Crystals on each side. 

The second bag attached to the closures contains crimp beads, silver plated spacer beads and beading wire. 

The picture really does not show how beautiful these pieces are.

I think the metal is Silver Plated, but I cannot be sure.
