Kleenex Slim Pack Facial Tissue 10 Count 3-ply (Pack of 12)

How do these packs open? Do they open on the end or are they perforated to open right down the middle? I want to put it in a handmade holder.

What size is each individual package?

Can we specify which package design when we order? I'm a guy and most of the ones I see in stores are very feminine-looking.

Would these fit in the side tissue dispenser on diapers bags?
