Ice Pack: Keep your Laptop Cool! Fits 14" and 15" Laptop perfectly!
Instructions: Pour 56 oz or 7 cups of water into a pitcher. Allow water to stand to release air bubbles. Fill cooler. When water reaches the top, push in the silicone cork narrow end first until flush (wetting the corks makes installation easier). Once the cork is installed, it cannot be removed. Screw the cap on and tighten all the way until there is no gap at the bottom of the cap, where it meets the spout rim. Pack will turn to gel in 20 minutes. Place pack in freezer for 12 to 48 hours.
