Two SONY TDG-BT500A active 3D glasses. - Brand: SONY - Model: TDG-BT500A - Type: Active 3D Glasses - Quantity: Set of 2 (One has a broken temple) Thank you for viewing. Used only a few times. They've been sitting on a shelf for a long time. The batteries were dead, so I haven't confirmed if they power on, but I can check if they work after replacing the batteries. It's a set of 2, but one of them has a broken temple as shown in the picture (the lens itself is fine). The box, instruction manual, etc. are all included.
