Heating Instructions

1. Please cover the wrap in a wet towel before heating. Place room temperature wrap evenly spread in the centre of a clean microwave turntable, not touching the sides of the oven. Ensure that any additional microwave features are turned off, such as "browning".

2. Heat in the microwave for 60 seconds (800W) or 40 seconds (1000W). If reheating, heat for an additional 15 seconds (800W) or 10 seconds (1000W). Please do not exceed 100 seconds total heating time.

3. Check to ensure temperature is suitable before application. Before reheating, check if the temperature of any part of the pack is too hot. Knead and rotate the pack to disperse heat evenly.
