The Copenhagen T Shirt suffered.
Some people said they could see it, but yet they could never find it in the same place. Strangely, if they did hold onto it, it was always blurry.
Sizing was difficult. Consumers could never figure out what the proper size was. Is your size root(2)/2?
Distribution was difficult too. Approximate half the distributions were imaginary.
Great, my shirt came, sized root(2)/2, and it's imaginary.
Total collapse followed.
