Privacy Protection: The privacy window film can block outside view, so you always feel safe when you are in your private space (Note: It is not recommended to use when you take a shower in the bathroom, because the degree of privacy is not very high.) UV and Anti-Glare: Our electrostatic window film blocks UVA and UVB rays to protect your skin and furniture from sun damage. It filters direct sunlight and prevents harmful glare, so you can spend time in a comfortable room bathed in soft natural light. Safe to use without glue: This electrostatic window film has an adhesive-free design and sticks securely to any flat, clean glass surface with just water. Made from non-toxic PVC, our window films are safe to use in any residential or commercial environment. No glue is used, which eliminates the release of harmful chemicals when exposed to strong sunlight. EASY TO APPLY AND REMOVE: Thanks to its electrostatic properties, you can apply this blind film in minutes without streaking - just cut it, spray enough water, apply the film and finally press it flat! It can be reused and repositioned multiple times and removes without leaving messy residue or damage. Remember to remove the protective film before installation. Endless Rainbow Effect Decoration: Our window film allows you to decorate smooth glass windows, doors with its unique patterns, which can also enhance the decoration of your space. It also creates a stunning rainbow visual effect when strong natural light hits it, bringing a special touch to your living room, kitchen, bedroom, office, home! (Note: there are no actual colors in the film itself, nor a colorful rainbow effect.)
