These are in 2-pack of excellent DLP link 3D glasses. Mint condition. Price is $45 shipped to cont. USA. Used once. They are made by 3DTV and carry HiShock brand on them. Bought them for Benq W1070 but had to return it. I paid $65 for them. They worked extremely well for the test that I had with 3D Gravity and other movies. Please note this is 4th Gen that is highly regarded on AVS Forum for Zero ghosting, sync doesn't drop at extreme angles, no red flashes. Just solid 3D glasses for DLP projectors.
