Brrnoo 2 Strabismus Correction Cards, Improve Visual Sense Amblyopia Coated Paper Training Cards with Red and Green Bars

Item as described.

Pictured with a standard Hoyle playing card for size reference. They are exactly as described. Two cards, each has a red side and a green side. They are close to the thickness of a playing card too and lightly laminated. I appreciate that the listing here on Amazon includes the instructions translated into English. The physical cards came with a sheet of instructions in Chinese.

There were supposed to be two cards in this pack, but there was only one. Please send the other one. Thanks.

All instructions in Chinese, so they are useless.

Not much to say,. It works as advertised.
