Daytime Privacy Protection - This reflective window film provides excellent daytime privacy because the exterior glass creates a mirrored effect when the exterior light is brighter than the interior light. Note: At night, the mirrored effect is reversed and the interior is visible from the outside, so consider drawing the curtains. Easy to Easy to install - This self-adhesive window film with thin adhesive is very easy to install and remove. Just use plenty of water on the glass surfaces to stick it. It can be easily removed by peeling the film from a corner and spraying it thoroughly with water. It leaves no residue and does not damage the glass. UV Blocking - Blocks 95% of harmful ultraviolet rays and reduces the sun's rays. Protects your skin and allows you to enjoy the sun with peace of mind. Also prevents furniture from fading. Thermal Insulation - This temperature regulating window film keeps you warm in winter and blocks heat in summer. Wide Applications - Suitable for offices,
