This video can better explain:
In addition to helping you find your missing item, foundmi also has a remote selfie option. Open the camera app from the foundmi app and my Stormtrooper becomes a remote shutter button! Amaze! Each foundmi unit also comes with an optional keyring or 3M stickers. Either loop to your keys/bag or stick to whatever you want to keep tabs on.
Dress: Kohl's (Yes, that is the Imperial logo from Star Wars!!)
Purse: Angelic Pretty
Stormtrooper Keychain: foundmi
