1. When used for waterproofing, please check for air leakage, then blow into the casing, and then pinch the mouth tightly to see if the casing becomes smaller. If it is still small, it will not leak and can be used.

2. Can not be worn for a long time. If you feel swelling and tingling on your fingertips, you should immediately clear the purple and raise your finger. It will gradually recover as before.

3. Dry it in a cool place after use and can be used repeatedly.

4. When it is not suitable to wear often, sprinkle some prickly heat powder or talcum powder to make it smooth.

5. Roll it up from top to bottom so that it can be removed and worn next time.

6. The nitrile finger cot has a rubber ring, which can work longer. Ordinary finger beds cannot work for a long time, which will swell the blood and cause unbearable pain

7. Our non-sulfur finger cots are not prone to chemical reactions after contact with precious metals. Sulfur-free composite technology eliminates the need for vulcanization of finger cots
