Corners need to be reinforced with taping as both mirrors arrived with the  frame having small cracks in one corner of each mirror.  I think the delivery method might be partly to blame as the first mirror packaging was quite damaged and the second mirror was left against a garage door was left against a garage door.  I didn’t know it was there and consequently opened the door and found it lying there flat on the ground!  I’m using both mirrors because I find them quite beautiful.  Just don’t know that I’ll order anything that expensive and fragile again from anywhere.
