Blocks the sun, Fights my washer

These curtains are amazing at smothering every bit of light-like ''did the sun even rise?'' But hey... the last time I washed a set, my washer went full WWE on the metal rings and tore them up. So now I admire them from a safe distance to avoid the laundry drama.

Good for the money

This is a good product for the price quality of thickness isn’t as good as others but what I expected for $11 a panel I would suggest buying it if finances are tight and you need something it helps Pictures show how much light it keeps out, specifically when the sun is shining directly into this room. Also the underside which is black.
