A stand-up pouch fitted with a water-activated calcium oxide heating sleeve — no food included. Just place your tiffin, sealed dabba, or packed container on top, add water to the pouch, seal, and it heats your food to 70°C+ in 10-15 minutes. No stove, no electricity, no microwave. Perfect for travellers, trekkers, and commuters carrying homemade food who just need a way to heat it on the go.
