RONHAN 2 Pieces 3D Movie Game Glasses 3D Red Blue Glasses for 3D Movies Games, 3D Viewing Glasses, Light Simple Design(Black)

So happy with this purchase! Any old-school 3D fan will be happy to know these work great, flat screen or CRT. Just flip 'em upside down if it's cyan/red and still feels comfy. Great buy for a great price! Plus super fun hunting down old red/cyan 3D movies and upscales. Fun!
