My sleep item. Custom-made blackout curtains.

Made to order, so I don't know the brand well.

It's so great when I want to take a nap during the day.

I am very satisfied with the sleep because it blocks 100% of the light.

When working hours switch between day and night, sleep is an important measure of health. As the saying goes, "Sleep is medicine," it would be good to have at least one personal item that is essential for your sleep.
