just so you know,
in Japan they sell bite-sized (2-bars, ~5cm long) Kit-Kats more than the original 4-bars sized Kit-Kat
at that size, it is way easier to just bite both bars rather than splitting individual bar
in fact, due to its length, it is more difficult to split compared to the normal sized especially when the chocolate is still hard
add to that, the wrapping is plastic,
in the normal Kit-Kat, the tin foil wrapping is very satisfactory when you split it
in the bite-sized, I just rip the plastic and chomp all of it
because it is "BITE-SIZED"
