Due to a variety of factors such as popularity and the global chip shortage, even until today it is still somewhat difficult to get your hands on a Sony PS5 console. This means that this has created a market for scalpers to profit from, where they snap up any available unit and then resell it at heavily marked up prices.
However, over in Japan, retailers are trying to take steps to counter these scalpers. One of those methods involves writing or drawing on the box of the console itself. For example, as report by VGC, retail chain Nojima Denki has taken to writing the name of the buyer inside the box of the PS5, and also removing the packaging of the controller.
