The Helmet Diamond Glass 4D is a protective front screen cover designed specifically for the Samsung J2 Core. It uses high-quality tempered glass with a 4D molded shape, which allows it to follow the curved edges of your display for more complete coverage than standard flat protectors. To keep your screen clear during daily use, the glass features an oleophobic coating that reduces fingerprints and oil smudges, while also providing resistance against scratches and moderate impacts. The kit comes in black and includes all the necessary cleaning and installation accessories to help you apply it smoothly.
