It is not at all a ARNAQUEEEUUUHH !!! It is you who do not read, see that what you want: it's called scotomisation (not No sodomy!) Even if you think queeeeuuuhh ... The dimensions are those of the pack ... In fact, because you have FORGOTTEN thickness, 1cm! Eh yes! And a rule like yours, with 1 cm thick, it is rather a clipboard, ah, ah, ah !!! Finally in the photo, because you HAVE LOOKED photo, indicated the measures in inchs and CMS NOT !!! So if you are not happy, take yourself to yourself and sco-to-mi-sa-tion, not Amazon !!!
