PRODUCT OVERVIEW

2689: PISTON,LINEAR ACTUATING CYLINDER.

Zzzzzzzzz. This screen protector is equipped with a specially designed anti-blue light that may help you sleep better at night. It softens the strong blue light from your phone, which can be hard on your eyes and trick your brain into thinking it’s daytime, disrupting your sleeping pattern.

Accidental bumps against sharp-edged dangers in your pocket or crushing falls onto stone-hard pavements are also no match for this scratch and shock-resistant screen protector. The Edge-to-Edge screen protector covers the entire front surface of your phone, while leaving room for a case, and comes in FSC-labelled packaging that can be recycled. This part is cataloged in the U.S.

Government catalog under NSN 3110-00-100-0735, indicating validated use in U.S. government and defense logistics supply chains.
