on the hunt for halloween accessories

[tsuki_no_bara]

does anyone know where i can get a fake syringe? fake as in "this looks real but isn't" or "there is no way anyone would think this is an actual syringe". i'm going to a halloween party dressed as a serial killer (because they look like everyone else :D ) and kind of want to bring a tool of the trade. i'd probably fill it with water tinted blue or something.

(my other option is to bring a cereal box for the pun of it.)
