Ignik Toe Warmers are designed to tackle the common issues found in typical air-activated warmers, offering improvements in both reliability and environmental impact. Key among these improvements is the enhanced packaging developed by Ignik, which keeps air out until the warmers are needed, ensuring they deliver safe, natural heat reliably for up to 10 hours. Another significant advancement is the eco-friendly design. Ignik Warmers are 98% biodegradable, and the natural minerals inside can be composted, contributing to reducing environmental waste. Additionally, each pair of Ignik Hand Warmers includes a reusable AirBarrier bag, allowing you to save any unused warmers for later, thereby minimizing waste. These warmers are versatile and provide long-lasting heat, making them perfect for various activities like outdoor sporting events, camping, hunting, or simply taking a walk. They are also an excellent resource to keep in your home and car for emergencies. Each package contains 4 pairs of individually packaged foot warmers, ensuring you have reliable warmth whenever you need it.
