They are well-folded so that they look like origami, so you don't want to spread them out when you clean your glasses.
But don't worry as they goes back to the original shape really fast!
See the youtube below.
The cloths are made in pleats so that the folds won't go away.
That's why they go back to the original shape when you just toss them up.
