Shrink-Fit Window Pack features crystal clear shrink film and double sided tape for easy installation. 

The shrink film insulates the window by keeping warm air in and cold air out, reducing energy expenditures. 

The film shrinks air-tight and wrinkle-free with the aid of an ordinary hand held hair dryer.  Stop cold drafts, helps prevent frost build-up and reduce condensation with this easy-to-use kit.
