This is a set of SONY 3D glasses and a transmitter. These nostalgic glasses were quite the talk of the town when they were released. [Set Contents] ・SONY 3D Glasses x 2 TDG-BR100 3D Glasses ・SONY 3D Sync Transmitter TMR-BR100 I used them with a Sony LCD TV, KDL-40HX800. I only used them a few times and they've been stored away, so in my opinion, they are in good condition. I can't confirm their operation as the TV is broken, but the power turns on without issue. *Please purchase batteries separately. Please purchase with the above in mind.
