Membrane film from the company GrizzGlass for protecting the tablet screen from scratches, damages, and fingerprints. It is easily applied and does not affect the touch function. It is a combination of tempered glass and protective film, as it has a ceramic coating for hardness like glass but also light elasticity like film. It is resistant to scratches, repels fingerprints, but reflects light. More durable than tempered glass. Compatible with Galaxy Tab S10 Ultra. See full description
