Modern Crystal Wall Light Fixture with Crystal Wall Lamp for Corridor Bedroom Living Room

Important, important! Operating instructions for twisting the crystal (remember this):
Just gently twist the screw until it is tight. Once it is tight, don't apply any more force to twist it further (remember, remember). Otherwise, the crystal may come off.
The screw on the crystal is bonded to the crystal piece using a special crystal adhesive. Due to the lever effect. If the screw and the screw holes on the metal frame are tightened, and then additional force is continuously applied to twist it, this will cause the crystal to come off. Remember to operate it this way. Just twist it gently until it is tight. Don't apply any more force to twist it.
