The packaging lies
A similar situation can be seen in this photo when we turn to the stationery aisle of the store, and this box of pencils. It’s yet another example of companies using packaging to make the consumer feel as if they are getting more than they actually are for their money. You’d expect at least 13 pencils in this pack, but you’d be wrong.
By using the window, and some extra pieces of cardboard it isn’t until they get home that a customer realizes that they only have 5 pencils and a larger than necessary packet. The only possible reason to do something like this is to make more profit from the people you’re selling to, and it’s pretty shady.
