KitKats (at least where I'm from) used to be wrapped in foil and a paper sleeve.

Kit-Kat and many other chocolate treats like Nestle Crunch and Cadbury were sold covered in aluminum(?) foil and wrapped with a paper band here in the PH prior to the early 2010's(?) before they switched to the plastic wrap.

The mini variety pack ones from the USA do still come covered with paper-lined foil(?) but those aren't the same aesthetically.
