The fabric lunch snack bags resemble a “brown paper bag” and instant hit with kids of all ages. The outside material is 100% cotton fabric. The bags are lined with water resistant-canvas fabric material, hook and loop closure, and it measures 12 1/2” tall x 11” wide unfolded. Click on last picture for inside look plus hook and loop closure. It is a versatile lunch snack bag with many uses. I use it to store my snacks and put it in tote bag for everyday use. It is NOT insulated to keep your food hot or cold. Cleaning – Machine or hand wash cold water and air dry. Return and Refund - I have a "no return" policy at this time. I will consider "return and refund" on a case by case basis but return shipping cost is the responsibility of the buyer and original shipping cost will not be refunded. ENJOY!
