Mom and I are making "green" reusable bags for your lunches! They are lined with waterproof nylon fabric that wipe out easily. They are washable and reusable (air dry not for dryer use). Velcro lines the top to seal the bag but we placed an easy pull tab above the velcro to make it easy to open. There are two sizes. Large and small. Head over to our etsy shop to see the different fabrics. This one by MODA by Lila Tueller called Woodland Bloom.
