Colourblind Test T-Shirt

Playing pranks is fun. Like putting Post It Notes on the laser of their mouse. And also unplugging said mouse, so they still can't figure out why their mouse won't work. This prank is one people can take with them. We've all had a colourblind test, where you have to read the number in the mix of dots. And if you can't see that number, bad news unfortunately, you're colourblind. That number has been taken out to make everyone think they should get their eyes checked.
