The Reusable Cold-Hot Pack is made of a durable material with durable seams, and is filled with special non-toxic gel. Just put it in a freezer or heat it up in a microwave oven at 750W for 20-30 seconds, then wrap it up with soft cloth and apply the pack to an injured body part for cold or hot therapy treatment to relieve pain, reduce swelling, and enhance healing. No matter how you want to use it – either as a cold compress or as a hot compress - it is always soft and flexible. The Pack maintains flexibility at temperatures as low as -4°F (-20°C) and keeps the required temperature for more than 60 minutes.
The sphere of application of the Cold-Hot Pack is not limited to its usage as a medical compress. Use it whenever you need to cool or warm up anything. Either you want to cool a bottle of water, or to preserve food, the Cold-Hot Pack is a useful thing.
