For US $57 each, you can buy (in Japan) telephoto, wide, and macro lenses for your mobile.
Our opinion: don't do it. Perhaps the macro is a good thing - but it's probably not worth the cash, and carrying it around will truly be a pain. And having a magnet (which attaches the lens) swinging from your phone is probably not a good thing either - even though we no longer use floppy discs, the magnetic strips on your credit cards probably won't like it.
