What is the point of "man sized" tissues? You blow your nose in them and what do you do next? The used bit is a very small amount of the total tissue so there is loads of un-snotted space about. Do you throw it away and waste all that space? If not, you're carrying round mucus in a bit of damp paper until you need it. Yuk! Why don't they just make them one blow sized so you don't feel guilty about wasting the excess?
I find those perforated tissues on a roll you can get to be the best idea.
