This is a set of two lunch bags. Lunch bag → Approximately 20cm x 20cm (Please check the photos for the exact size) The fabric is a sturdy oxford cloth, so it's made with a single layer without lining. (When hanging to dry, I shape it, and we use it without ironing at home.) There may be some size discrepancies, but these are handmade by an amateur hobbyist, so please be understanding of the details.
