It's always smart (and handy) to have a little light with you. Find the keyhole in your front door or car, look for something you might have dropped or add a little light to a dark path - there are so many uses! A bright LED light illuminates with the press of a button, lighting up the main engine of this little space craft or astronaut. Press the button and it will light your way. Clip ring makes it easy to add keys and attach the keychain to a backpack, daypack or bag. Sold individually, there are four varieties!
