Using a sharp pair of scissors, remove the nail tip and the toothbrush.
Cut a small hole in the spring lock and drill a hole for the nail to go into.
Take a nail and put it into the springlock.
Slide the spring to one side of the lock.
Slide it back to the other side.
Slide both halves of the spring back together.
Slide back the spring and the lock together.
Slide in the pin and nail, using a flat-head screwdriver.
Take care to not puncture the spring or the lock, or else you could tear the spring off the pin.
