Handmade Foodman Mini lunch bag. The outer fabric is khaki for the lid and a dark denim-like fabric for the rest. The inner fabric is nylon-like. The lid is secured with Velcro. It's made in a slightly larger size, so there's room for chopsticks and an ice pack. Made of fabric, it can be machine washed in a laundry net. I use it myself and wash it every time. (There may be wrinkles and some color fading from washing.) It is not waterproof, so while the Foodman lunch box is designed to prevent leaks, if you are concerned, we recommend putting it in a Ziploc bag or similar before using this bag. I use a home sewing machine. I make them carefully, but they are handmade by an amateur. For those who understand this. #Foodman #FoodmanCase #FoodmanHandmade #FoodmanMini
