Review on Juvale Corrugated Cardboard 📦 Sheets: Reliable Packaging & Shipping Supplies by Richard Simmons

I was going to return this because it's too small but realized I could use it to insulate windows this winter and add front door privacy. So if I need to look out the window of the door, all I have to do is remove the piece of cardboard for a moment. In another house I stayed in I used cardboard for the diamond windows and you didn't notice the window on the outside of the house so passers-by probably never noticed I had glass windows on the door. This saves me time and hopefully money on my electricity bill.
