Warmables was born in 2009 with the idea of sending a young boy off to school with a warm meal in his lunch box. The challenge was keeping it warm til noon. I am that boy's mom and with his help, I succeeded. My son is now in college and we have sold thousands of our Food Warmer Sleeves throughout the US. Thinking back, the hardest part was explaining to concerned parents that keeping food warm for a few hours is perfectly fine. The concept caught on. While many companies now offer mass-produced heated lunchboxes, Warmables is still HANDMADE, naturally, and sustainably made. What I am most excited about and proud of is that we still source all our materials and supplies right here in the USA.
