The Grabber Toe Warmers are air-activated toe warmers that will keep toes toasty for over 6+ hours. No shaking or kneading required, just open the packaging to start the process. Warmers are standard equipment for skiers, snowboarders, hunters, campers, hikers, birdwatchers or anyone who enjoys outdoor activities when the weather is cold. Warmers are widely used as portable, long-lasting heat therapy. All Grabber Hand and Toe Warmers are designed for a one-time, disposable use. Each package contains one pair of toe warmers.
