These Wallet Closures are the bars that sit on the top edges of wallets & purses. You put the back on one side and the front (with hole) on the other and pull them together to close your wallet up tight. The flip part clicks in place nicely for security. They are prepackaged and come with 10 screws (8 are needed, 2 are extra). Each bar has protective plastic that needs to be removed during installation.
