My personal sleep item: perfect light-blocking sleep mask

I always want to do it.

Perfect light-blocking sleep mask.

Since it was a gift, at first the strap felt tight, so I loosened it a bit and it was a bit uncomfortable in various ways, but now I can't sleep without it. I gently close my eyes, it’s comfortable, and it blocks out light perfectly, so I sleep deeply. When I put up blackout curtains, use a knee cushion, and do various things, it sometimes gets in the way and I sleep worse. I think an eye mask is the most basic item for a good night's sleep. It's better to buy several rather than just one.
