The vast majority of these products have had piano black bezels and normally black on the back too. The vast majority of Rakuten Kobo e-readers also have black bezels, but there have been outliers, such as the Kobo Touch, Kobo Glo, which had a white body. The company has always had multiple white e-readers, as well as black ones. Whether these devices have a domestic or international release, they tend to have black bezels and a black plate. I’ve noticed that these brands tend to play it safe, avoiding risks associated with white bezels or other colors.
