Warm use: Place in a clean microwave in 30 second intervals until optimal temperature is achieved. Test temperature before using; wrap should feel warm to the touch, not hot.
Never leave wrap unattended in the microwave.
Cold use: Seal in a plastic bag and leave in the freezer for at least 6 hours. Wrap may be left in the freezer indefinitely until needed.
To Wash: Machine wash and dry outer cover. Do not get grain pack wet.
