Thank you for viewing from among many items (*^▽^*) I made an eco-bag with a penguin pattern! There is no lining, but it is sewn with a bag stitch to make it durable. It is a plastic bag-style eco-bag. It can be folded up small. It is washable. To fold it, fold it in thirds lengthwise as shown in the photo, then fold it up from the bottom and secure it with the rubber band for compact carrying. Size * Height: 34 cm * Width: 26 cm * Depth: 14 cm (There may be some errors) I tried making the gusset large. I think it's easy to put in a lunch box! It is a handmade item by an amateur, so I would appreciate it if you could overlook the small details. Thank you for your understanding and purchase. * There are marks from the chalk pen, but they will disappear over time.
