Very nice locket, although you'll probably want a little better chain.  But when buying something like this the chain is an afterthought, and my wife will probably use a different chain.

Inserting pictures is virtually impossible.  There's a thin plastic piece with 4 tabs that has to be popped out, and it's impossible to reset all 4 tabs.  I got 3 in and it fell out, then one of them got scratched during the process.  I instead removed the plastic and put my pictures in with two sided tape.
