The WB27 is a tempered glass screen protector from the brand YESIDO, designed for advanced protection of your smartphone's camera lens. The highly durable 9H hardness glass is surrounded by a black aluminum frame, which provides additional reinforcement to the camera lens. The adhesive used prevents the formation of air bubbles and makes it easier to push them out if they occur. Thanks to this frame, the application of the glass is perfect on the first attempt.
