This Cobber cooling scarf is ideal for during hot days. It works like this: you put the Cobber in the water for about 20-30 minutes. In this way, it is activated. Squeeze out the excess water and, if necessary, allow the Cobber to dry further as desired. After this, the Cobber feels very cool to the touch; you can now easily place it on your neck or tie it around your forehead. It has a long-lasting effect, up to 5 days in a row. To re-cool the Cobber after a few days, you need to put it in the water again for a few minutes. It can also be used as a hotpack or icepack. To use it as an icepack, you must first activate it in the manner described above. Then the Cobber should go into the freezer for another 20 minutes. To use the Cobber as a hot pack, you must first let it dry completely. Now place it in hot water for about eight minutes. Or use the microwave: activate the Cobber according to instructions. You can now put it in the microwave for 40-50 seconds at 600 watts. Washing instructions: the Cobber should not go in the washing machine, wash it with a hand wash. The water may be 30 degrees, with a mild detergent and possibly a small splash of natural vinegar. The colors may rub off. Do not leave the Cobber in soapy water. Further instructions and warnings can be found on the package insert.
