The Fingerless Edition gloves and Professional Edition gloves can be washed in warm water. For Master Edition gloves, the batteries must  be removed before washing in warm water. After washing the gloves, they should be dried in a well-ventilated area. Avoid exposing them to direct sunlight, dry cleaning, or machine drying.

Laboratory test results, simulated glove storage and use, the graphene heating piece 180 degrees folded 10,000 times without exception, the heating piece can be normal heating work.

The Master Edition gloves are set at three temperatures, 40/50/60 degrees Celsius. The laboratory test standard is at room temperature 20 degrees Celsius, the graphene heating piece can theoretically reach the above three temperatures. When the ambient temperature drops, the power of the heating piece remains unchanged, and the actual maximum temperature achievable will change with the ambient temperature.

Our Master Edition gloves can still be switched on and off and adjusted gears normally after being placed in a laboratory environment at -35 degrees Celsius for 1.5 hours, and the graphene heating piece and batteries also work normally.
