I'm selling this because I just bought it, but the operating environment wasn't compatible with my setup. This is a set of the smart glasses本体 and three genuine accessories. The cap marked with the red frame in the third image, which is included with the accessories, is missing, but it doesn't affect the operation. I believe all other accessories are included. The smart glasses themselves are in very good condition. I'm not very good at explaining how to use the smart glasses, so please understand.
