1/8″ Insulated Metalized Mylar Double Foil Bubble, 16″ X 125′ Per Roll

I lined my cats boxes (plastic tubs with hole in the side) and it keeps them warm and dry (cuts condensation). I love this material. Tough, double-sided. Great product! I also made cat pads and even one for my 97 year old mom. Keeps them all from losing body heat. Yes!
