This is a handmade Foodman Mini lunch bag. The outer fabric has a light purple lid and a dark denim-style 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 one myself and wash it every time. (There may be wrinkles and some color fading from washing.) It is not waterproof, so while the Foodman lunchbox is designed to prevent leaks, if you're concerned, I 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
