Add a fitted protective layer to a 13.3-inch MacBook Pro display without changing the notebook itself. CELLAIRIS 11-0078533 is a screen-protector film specified for that screen size and MacBook Pro fit. It addresses the display surface directly, making it relevant when the requirement is screen coverage rather than a sleeve, shell, or keyboard accessory. The 16:10 display format aligns with the 13.3-inch MacBook Pro screen named for this film. That model-specific targeting matters because a film intended for a different diagonal or aspect ratio can leave edges exposed or interfere with the active display area. Select this accessory for MacBook Pro systems with the stated 13.3-inch screen specification; no claim is made here for other notebook generations or sizes. Film construction distinguishes this item from external laptop protection such as cases and carrying covers: it is intended to sit at the screen interface. Keep the scope narrow when matching accessories: this is a display film, not a replacement panel, adapter, dock, or enclosure. The compact accessory format suits users who need protection focused on the notebook display while retaining the original computer hardware and its normal desktop footprint in use.
