Reusable sandwich bags are perfect for lunch on the go, whether you're packing your bag for work or a day trip! They are just the right size for just about any sandwich. They are lined with food safe laminated cotton, making cleanup a breeze! Simply flip the bag inside out and wipe clean with warm, soapy water then lay flat to dry. You can also toss them in the washer, but it's recommended to dry them on a low heat setting to prolong the life of the liner.
