The check fabric is 50% cotton and 50% polyester. We used a fabric that is not too stiff and not too soft, combining the wrinkle resistance of polyester with the comfortable feel of cotton. The handles have a stiff interlining to prevent them from losing their shape, and the lining is a single-sided quilted nylon fabric, making it easy to put things in and durable for long-term use. Since it is not very thick, it can be folded and put into a school bag or other bag. To prevent the bottom from dragging when the lesson bag is hung on a first grader's low desk, we have attached a ribbon-like loop on the inside of the handle. All fabrics are made in Japan and carefully sewn with a sewing machine, and finished with a sparkling patch. You can wash it as usual. This is a popular check series that customers repeatedly purchase, saying it is very easy to use and does not lose its shape even after many washes.
