Miếng dán chắn sáng Manta

These stickers are surprisingly effective at covering the tiny LED on my router—no more blinking light keeping me awake. They peel off cleanly, too, which I was worried about.

Was about to toss my router due to that blinding blue light, but these stickers cut it out completely without leaving any sticky residue when I peeled one off to reposition. Each sheet has multiple sizes so I covered both my power strip and monitor in under a minute.

After a few nights, I'm amazed at how those tiny blue lights on my power strip just disappear — the stickers block the glow completely without leaving any residue. The matte finish blends into the plastic so well you'd never know they're there.
