GreenSmart lunch boxes are made from a material called Neogreene. Neogreene is similar to the commonly used material Neoprene, but avoids the use of chemicals and is completely environmentally friendly due to its waterbased ingredients. Making the material uses 25% less petroleum, 25% less energy, and eliminates toxins that can harm our air and water sources. The Margay Insulated Lunch Case is a new take on an “old school” lunch box. Its design is simple and practical with one spacious compartment and split exterior pocket. The Margay is perfect for packing lunch.
