'Reuse Reduce Recycle' removable indoor/outdoor UP-WORD sticker can be used on most any precleaned surface. This sticker collection was created to inspire anyone to take even better care of this earth as best they can. Every little bit helps and so consider using a reusable water bottle instead of using and throwing out  a disposable bottle.  I LOVE the idea of placing any sticker from this collection on a vehicle or in a classroom, locker, mirror or fridge ... anywhere to offer wise and encouraging words to inspire people to be part of a movement to create less garbage.
