FREE Manta Blackout Stickers

I was skeptical at first, but these stickers block out even the tiniest sliver of light from my alarm clock, making my room pitch black for sleep. The adhesive is strong but leaves no residue when I repositioned one to test it.

These stickers are perfect for covering the tiny blue LED on my monitor—no more light pollution while I sleep. They go on easily and stay put without peeling.

The adhesive holds really well on my window frame without leaving any residue when I peel it off. I’ve finally stopped waking up at sunrise thanks to these.
