Contains 10 pairs of Hand Warmers and 8 pairs of XL Warmers
Each hand warmer delivers up to 10 hrs. of warmth; each XL warmer delivers up to 24 hrs. of warmth
Air activates the warmers, but the resealable (and recyclable) AirBarrier™ pouch zips closed to keep air out, allowing you to store open warmers for up to 72 hrs.
After use, you can cut open the warmers and compost the minerals inside (note: the warmer sacks themselves are not compostable or recyclable and must be thrown away)
