A tiny little capsule that you can wear around your neck! The hole up top is pretty tiny, so if you use a larger jump ring than the ones linked below or have a sloppy printer, you can open it up a bit by heating up a needle or paperclip and poking it through. Of course, you can also scale up the entire model.
