Reusing Square Kleenex Boxes

I have Kleenex (facial tissue) all over the house, almost every room. Instead of constantly buying the small square box that fits in the common decorative Kleenex holder, I keep reusing the first box, open one of the side flaps, grab a 2 inch stack from the cheaper box, fold over the Kleenex and put inside the old empty square box, close the flaps and slip it back in the decorative holder. The small square boxes are more expensive and there is no need to keep buying them. The original is easy to refill and use so the Kleenex keeps its shape in the holder.
