When ironing, pull out the lining (aluminum sheet) and iron only the outer fabric. ◎ The fabric has been pre-washed before production. ◎ Due to the nature of the fabric, there may be neps (fiber clumps) or color fading. ◎ Purple chalk pen is used. It will disappear naturally after washing or with time, so please rest assured. ◎ Lunch boxes, trio sets, and chopstick sets are not included in the product. While we make them with care, they are handmade, so there may be slight misalignments, distortions, curved seams, and double stitching. We appreciate your understanding when purchasing (^^) 《About Shipping》 We will ship in an envelope after placing the item in a plastic bag.
