I rediscovered the mini-magnetic phone lenses I bought a while back. I have a telephoto, fish eye, and macro lens you can attach to your phone or webcam. All you need to do is stick the metal rings around your phone lens, and the mini-magnetic lenses will stick right on. I no longer need the fish-eye since my phone has that effect built in, but I am a fan of the macro lens. I decided to use it over the weekend on some of my nail polish and other random items.
