PRODUCT OVERVIEW

28943: CRYSTAL UNIT,QUARTZ.

VANITY UNIVERSAL is a special film with a practical millimetric measuring grid which allows it to be cut precisely and modelled to fit the display of any electronic device.When the display is on, VANITY UNIVERSAL is a scratchproof, totally transparent screen protector, when the display is off or on stand-by, VANITY UNIVERSAL transforms the surface of the iPhone® 4 into a perfectly reflective mirror.Thanks to the ULTRA-THIN MULTI LAY ERS TECHNOLOGY, 4 layers of film can be applied without affecting the thickness or transparency of the screen protector. Ultra-thin multilayer technology: - Scratch-proof coating; - Photoactive mirror; - Ultra transparent core; - Static adhesion surface. This part is cataloged in the U.S.

Government catalog under NSN 4820-00-029-0237, indicating validated use in U.S. government and defense logistics supply chains.
