I'd like a stick that matches the livestock sticks in style, that basically says "Help yourself to this stuff" and can be put over a pile of things on your street that you are giving away. Perhaps it could "unlock" things set directly under it? if you're planning on making more street-stuff lockable, which I fervently hope you do.
It could have a little Glitch hand on it, instead of piggy nose, feather, or butterfly symbol.
