Glass from the company Techsuit for protecting the tablet screen from scratches, damages, and fingerprints. It is easily applied and does not affect the touch function. Its special treatment makes the tablet screen visible only from the front, preventing visibility from any angle. This protection is useful if you frequently use public transportation and do not want others to look at your screen. However, it is not suitable for gaming or video watching as it darkens the screen. Compatible with Galaxy Tab S9. See full description
