Review on Aviditi 📦 Double Corrugated SP3636DW Length by Carlos Massey

I work nights and bought this as a cheap and easy way to block out the light in my room in the morning. I just bent one end and put two in the windowsill so I can push one out into the sunlight when I get up. They add an extra layer under my blackout curtains to keep the light out. They are just the perfect size for my windows.
