So we have seen these in our RPGs for years and years. Sometimes we see complete lists of what they actually are, buy by and large, for most of us, we just assume its stuff that thieves use and we leave it at that.
Not any more. Now you can get your very own set right over at Dude I Want That! Its a great site filled with all manner of useless....er, ful, stuff. You can even get jelly fish in a bowl! How cool is that.
