You need the 5 inch wide by 3 inch high Batman Symbol Sticker so you can tag all of your possessions with the popular Batman symbol! The Bat logo is recognized world wide as a symbol of justice…which is absolutely perfect for keeping your lunchbox, locker, zeppelin, stereo, instrument, frisbee, cooler, farm animals, 12 inch bowie knife, cookie jar, tricycle, water bottle, beer helmet, espresso machine, weed whacker, sno-cone maker, or fruit bowl proudly emblazoned with said logo(not for most of that stuff…’tis just a sticker)! I think I got everything, right? At least everybody will know how much of a Batman fan you are!
