This is the new government issue ration heating system. Instead of the old style water activated MRE Heater, this is a Diethylene Glycol fuel gel. Government approved and combat proven! Just open package, squeeze out gel and light it. Burns hot enough to boil a canteen cup of water for up to 5 minutes, or to heat an MRE main course. Non-toxic to use. However you want to avoid skin and eye contact. Not an edible gel. Gov't issue box of 3 individual gel packs. Gel also works exceptionally well as a fire starter. Great for survival and emergency kits.- Á©Àº ÇǺγª ´«¿¡ ´êÀ¸¸é ¾ÈµÇ¸ç ½Ä¿ë¸ñÀûµµ ¾Æ´Õ´Ï´Ù- Á¡È ½Ã¿¡µµ À¯¿ëÇÏ°Ô »ç¿ëÇÒ¼ö ÀÕ½À´Ï´Ù- ¼¹ÙÀ̹ú¿ëÇ°À̳ª ±¸±ÞÇ°À¸·Îµµ »ç¿ë °¡´ÉÇÕ´Ï´Ù
