Grabber Large Hand Warmers can now be turned on and turned off! Simply take warmers out of individual package and expose to air. For best results, use warmers in an enclosed area with air, such as a pocket or glove.
If there is still heat left when you are finished using the warmer, place in the Grabber® Air-Lock bag, squeeze out excess air and zip it shut.
- You may repeat this process until 10 hour duration is up.
