You can watch videos, etc., in the bath. It can be attached to the wall with magnets. External dimensions: 32 x 23.5 x 3 cm Film area: 28.5 x 20 cm These are approximate sizes as they were measured by an amateur. I don't know the inch size. There are fine scratches on the film area. The film's pressure is weak, so the tablet cannot be fixed. I think it will be fixed if you put a handkerchief, etc., under the tablet. (See photos 7-9) (Tablet and handkerchief are not included) It has been stored at home for a long time. Please purchase with your understanding. Thank you for viewing.
