RMH Cardboard 3D Glasses.
The original, cardboard 3D glasses with cyan/red lenses. Lens materials have no textures, so can be changed to any colour via the albedo property of the Unity Standard shader.
As always, for a better impression of the asset inside the Unity engine, please view the YouTube video in the screenshots section.
